Functional Description
The TLE 6214 L is a dual-low-side power switch which has two parallel inputs to control the 2 power DMOS switches, as well as by an 8-Bit SPI for control and diagnostic feedback. The power transistors are protected1) against short circuit, overload (current limitation), overtemperature and against overvoltage by an active zener clamp. The IC has a load current proportional current output for current control applications. The diagnostic logic recognises a fault condition which can be read out via the SPI or the parallel status outputs (depending on the IC configuration).
Output Stage Control: Parallel Control or SPI Control The Output stages can be controlled by parallel Inputs or by SPI command. The IC can be programmed (by SPI) to switch the outputs according to the parallel input signal, to the corresponding SPI command bit or to a combination of these two signals. IN 1,2 Both, parallel inputs and respective SPI databits are high active. Truth table for Output control

Switching speed / Slew rate: The switching speed / slew rate of both channels can be configured by SPI for slow or fast switching speed (1:5) for each channel individually. Overtemperature Behaviour: Each channel has an overtemperature sensor and is individually protected against overtemperature. As soon as overtemperature occurs the channel is immediately turned off (without fault filtering time) and the overtmperature information is reported by diagnosis. In this case there are two different behaviours of the affected channel that can be selected by SPI (for all channels generally). Autorestart: as long as the input signal of the channel remains on (e.g. parallel input high) the channel turns automatically on again after cooling down. Latching: After overtemperature shutdown the channel stays off until the overtemperature latch is reset by a new L H transition of the input signal. Note: The overtemperature sensors of the output channels are only active if the channel is turned on. As soon as the IC temperature (Temperature of the whole IC) reaches a specified level an overtemperature warning will be indicated.

Low Quiescent current mode (Sleep mode) : By SPI Command the device can be set to Sleep mode. In this mode all outputs are turned off, the diagnosis and biasing is disabled, the diagnosis and the on/off register are reseted and the current consumption drastically reduced. A wake up is done by sending a wake up command by SPI. A specified time (twake) after this command the IC is fully functional. The configuraton register (exception channel on/off register) values are not influenced by the sleep mode. After wake up the outputs are Off, except the outputs are controlled by parallel inputs. Overload Protection: The IC can be programmed to react in different ways to overload. Current limit 1: In this mode the IC active limits the current to the specified "Current Limit 1". If the current limitation is active for longer than the fault filtering time this fault is reported and stored in the Fault register. Current limit 2: If this current limit is active for more than the specified "Overload switch off delay time" the affected channel is turned off and the fault is reported and stored in the fault register. To turn on the channel again this overload latch has to be reset before with an L H transition of the input signal (parallel /SPI depending on the programmed operation). The two operation modes can be changed during operation of the channel.
Pin description:
OUTPUT 1,2 - Drain pins of the two channels. Output pins and connected to the load. GND - Ground pins. IN 1,2 - Parallel Input Pins of the two channels IS / Fault / ST1 -Configurable output pin. Depending on the configuration (done by SPI command) it has three basic functions: a) General Fault pin. This is a general fault pin (open drain) which shows a high to low transition as soon as an error is latched into the diagnosis register. When the diagnosis register is cleared this flag is also reset (high state). This fault indication can be used to generate a C interrupt. b) Sense Function. In this configuration the analog output signal represents the value of the load current: Sense Current proportional load current channel 1 Sense Current proportional load current channel 2 Sense Current proportional load current of both channels (ID1 + ID2) c) Status Output for channel 1: The Status output shows the same level as the input signal of channel 1 as long as there is no error and the inverted input signal when any kind of error occurred at channel 1 VS - Logic Supply pin. Used to supply the integrated circuitry. CS - Chip Select of the SPI (low active) SO / ST2 - Configurable output pin. Depending on the configuration (done by SPI command) it has two functions: a) Signal Output of the Serial Peripheral Interface b) Status Output for channel 2: The Status output shows the same level as the input signal of channel 2 as long as there is no error and the inverted input signal when any kind of error occurred at channel 2 SI - Signal Input of the Serial Peripheral Interface. The pin has an internal pull down structure. SCKL - Clock Input of the Serial Peripheral Interface. The pin has an internal pull down structure

SPI
The SPI is a Serial Peripheral Interface with 4 digital pins CS and an 8 bit shift register. The SPI is used to configure and SCLK program the device, turn on and off channels and to read SI detailed diagnostic information. SO Note: The default setting of the TLE614L is to use the the SO/ST2 pin as status output pin for channel 2. To activate the SO function of the SPI the command "I/O Configure" (see. SPI commands: No.3) has to be used to reconfigure the IC. (e.g. 0111 xxxx)
SPI
SPI Signal Description: CS - Chip Select. The system microcontroller selects the TLE 6214 L by means of the CS pin. Whenever the pin is in a logic low state, data can be transferred from the C and vice versa.

CS SI Serial input data MSB first SO Serial output (diagnosis) MSB first
CS = H : Any signals at the SCLK and SI pins are ignored and SO is forced into a high impedance state. CS = H L : * diagnostic information is transferred from the diagnosis register into the SPI shift register. (in sleep mode no tranfer of diagnostic information) * serial input data can be clocked into the SPI shift register from then on * SO changes from high impedance state

to logic high or low state corresponding to the SO bits
CS = L : SPI is working like a shift register. With each clock signal at the SCLK pin the state of the SI is read into the SPI shift-register (falling clock edge) and one diagnosis bit is written out of SO (rising rising edge). CS = L H: * transfer of SI bits from SPI shift register into the internal logic registers * reset of diagnosis register if sent command was valid To avoid any false clocking the serial clock input pin SCLK should be logic low state during high to low transition of CS. SCLK - Serial Clock. The serial clock pin clocks the internal SPI shift register of the TLE 6214 L. The serial input (SI) accepts data into the input SPI shift register on the falling edge if while the serial output (SO) shifts diagnostic information out of the SPI shift register on the rising edge of serial clock. It is essential that the SCLK pin is in a logic low state whenever chip select CS makes any transition. SI - Serial Input. Serial data bits are shifted in at this pin, the most significant bit (MSB) first. SI information is read in on the falling edge . Input data is latched in the SPI shift register and then transferred to the internal registers of the logic. The input data consist of 8 bit, made up of x control bits and y data bits. The control word is used to program the device, to operate it in a certain mode as well as providing diagnostic information (see SPI Commands). SO - Serial Output. Diagnostic data bits are shifted out serially at this pin, the most significant bit (MSB) first. SO is in a high impedance state until the CS pin goes to a logic low state. New diagnostic data will appear at the SO pin following the rising edge.

Channels on / off : Turns on / off the power outputs (if configured for serial control) Ch1 : Serial control bit of channel 1 0: Output off(default) 1: Output on Ch2 : Serial control bit of channel 2 0: Output off(default) 1: Output on After activation of the low quiescent mode by the "sleep" command, the outputs are turned off and the serial control register is set to default values. 8. No Command : No valid command and will not lead to an reaction (register value change, switching channels, ...) of the IC. After Chip Select giong L H the diagnosis register will not be reset.
SPI Diagnostics:
As soon as a fault occurs for longer than the fault filtering time (exept Overtemperature; no filtering time), the fault information is latched into the diagnosis register (and the Fault pin will change from high to low state). A new error on the same channel will over-write the old error report. Serial data out pin (SO) is in a high impedance state when CS is high. If CS receives a LOW signal, all diagnosis bits can be shifted out serially. If the sent command was valid the rising edge of CS will reset all diagnosis registers and restart the fault filtering time. In case of an invalid command the device will ignore the data bits and the diagnosis register will not be reset at the rising CS edge.

For Full Diagnosis there are two diagnostic bits per channel configured as shown in Figure 1. Bit 6 and bit 7 of the diagnostic register are not used and always H. Normal function: The bit combination HH indicates that there is no fault condition, i.e. normal function. Overload, Shorted Load or Overtemperature: HL is set when the current limitation gets active, i.e. there is a overload, short to supply or overtemperature condition. The second reason for this bit combination is overtemperature of the corresponding channel. Open load/ Under current: LH is set when open load (in off state of the channel) or under current (in on state of the channel) is detected Short to GND : LL is set when this condition is detected (in off state) Channel Overtemperature Flag: In case of overtemperature in any output channel in on state the overtemperature Flag in the SPI diagnosis register is set. This Bit can be used to distinguish between Overload and Overtemperature (both HL combination). IC Overtemperature Warning Flag: When the IC logic temperature exceeds typ.170 the IC Overtemperature Warning Flag will be set in the SPI diagnosis register.
Parallel Status Output Diagnostics :
Parallel diagnostic outputs (open drain) change state according to the input signal of the corresponding channel. As soon as an error occurs at the corresponding channel ( Overload, Overtemperature and Under current is detected in on state and Open load, short to GND also in off state) the Status output shows the inverted input signal. A fault is detected only if it lasts for longer than the fault filtering time. This fault information is not latched.

Analog Current Sensing :
The TLE6214L provides an analog current sensing function for both output channels. By SPI configuration the multifunctional pin CO1 can sink a sense current proportional to the load current of one/ both of the two output channels1). The specified current range and accuracy is described in the electrical characteristics "5.Analog Current Sense Output". To achieve the specified accuracy for current sensing the voltage at the CO1 pin must always be UCO1 2V.
