So it is perfectly suited to interface control IC with Power Switches in low side or half-bridge configuration. TD310 includes a current sense comparator which inhibit the output drivers in case of overcurrent. An alarm output signals the even to a controller. TD310 also includes an uncommitted op-amp which can be used for current measurement (as an amplifier before the A/D input of a microcontroller) of for other general purpose. Programmable undervoltage lockout and standby mode make TD310 suitable for a large area of environment and application. Typical applications are low side IGBT and power MOSFET drive in three phase systems, pulse transformer drive, and general purpose pulse drive.

The bridge rate can be calculated in relation with the expected UVLO protection level as follows : VUVLO x -------------------- R1 R1 + R2 = 1.2V (where R1 is the lower resistor of the bridge) The internal resistor sets the default UVLO value to 12V (*) and might influence the external bridge rate if the values of the external resistors are too high. Moreover, the internal resistor ratio is accurate, but the the tolerance on the absolute value of each internal resistor (typically 140k and 1.26M) is about +/-20%. If an external bridge is used, we recommend to choose resistor values not greater than 10k. The standby threshold value depends of the UVLO value as follows: Vstdby = 0.7/1.2 VUVLO Both UVLO and stdby functions can be inhibited by connecting the UVLO/stdby pin to VCC+ via a pull up resistor (ex 150k). The following table summarizes the functions of the TD310 : Pin Config 16 UVLO/ stdby H 9/11 Sense+/ Sense+>Normal 1 +<+>+ 2 3 L M HZ OK Configuration 1 : UVLO/stdby = H The TD310 is in a normal consumption state (1.5mA), the operational amplifier is normally functioning and the buffer outputs are determined by the sense comparator inputs, the enable inputs and the buffer inputs. Configuration 2 : UVLO/stdby = L The TD310 is in a low consumption state (standby mode 30A), the buffer outputs are set to low state and the operational amplifier is in high impedance state. Configuration 3 : UVLO/stdby = M The VCC supply voltage is between VUVLO and Vstdby (**). The TD310 remains in a normal consumption state and the operational amplifier is normally functioning but the buffer outputs and the alarm pin are set to low state. (*) (**) If the UVLO level remains unadjusted, it is recommended to bypass the UVLO/stdby pin with a 1nF capacitor. If the supply voltage falls below Vstdby, the TD310 is set in standby mode (configuration 2). 4/9 TD310 TIMING DIAGRAM TIMING 1 Input A/B/C tdH tli tdL Output A/B/C TIMING 2 Input A/B/C Output A/B/C ts tAi Sense tA tAi teL Alarm Enable teH Under Voltage 5/9 TD310 TYPICAL APPLICATIONS Figure 1 : HALF BRIDGE DRIVE IN THREE PHASE MOTOR SYSTEM High voltage VCC MCU signals Stby Pulse controlled inputs ON OFF INA INB INC Level controlled input Enable Alarm VCC UVLO Standby OUTA OUTB Pulse transf LOAD OUTC VCC LOGIC Sense+ Sense Shunt TD310 OA output OA input + OA Input- GND GND 6/9 TD310 Figure 2 : THREE PHASE MOTOR LOW SIDE DRIVE +400V MICRO CONTROLLER High Side Driver HS STBY A B C En IT Stby INA INB INC Enable Alarm VCC VCC UVLO Standby M OUTA OUTB OUTC VCC LOGIC Sense+ Sense Shunt TD310 ANA OA output OA input + OA InputGND GND Figure 3 : LOW SIDE DRIVE VCC LOAD LOAD LOAD VCC Stby INA INB INC Enable Alarm LOGIC UVLO Standby OUTA OUTB OUTC VCC Sense+ Sense Shunt TD310 OA output OA input + OA Input- GND GND 7/9 TD310 PACKAGE MECHANICAL DATA 16 PINS - PLASTIC DIP Millimeters Dim.
