Automotive Dual High Side Driver
This device called "Flasher Lite" is a dual high side power switch dedicated for automotive applications. In comparison with mechanical relays, this device offers higher reliability as well as protection and diagnostic features. The device consists of two independent 25m Rdson switches in a surface mount package. It can be directly interfaced with a microcontroller for control and diagnostic functions and includes a current recopy function. The device is fully protected against overcurrents, short-circuits and incorporates an overtemperature shutdown. It can be directly and continuously supplied by the battery and offers a very low quiescent current in standby mode. * Designed for Automotive Applications * Junction Temperature Range from - 40C to 150C * Operating Voltage Range from 8V to 40V * Reverse Battery protected up to -14V with no external components * Surface Mount Package, Thermally Enhanced * 25mOhms max Rdson per Channel at 25C * Independant Status Lines, one per channel * Overtemperature Protection with Hysteresis * Open Load Detection in On-State * Short-Circuit Protection * Loss of gnd, loss of Vbat protection * Independant Current Recopy, one per channel * Under Voltage Shutdown * ESD Protection 2kV * Current Limitation greater than 25A to Allow load Inrush Current * Standby Current less than 1uA at Vbat =14V and ambiant temperature

Vbatc Supply Voltag
These are the power supply pins of the device. These pins are directly connected with the lead frame of the package and are tied to the drain of the switching MOSFET. These pins can be directly connected to the battery voltage. In addition to their supply functions, these pins participate to the thermal behaviour of the device in conducting the heat from the switching MOSFET to the printed circuit board. Vbatc provide the supply voltage to the control die. Pins 3 and 4 are the output 1 terminals. Pins 17 and 18 are the output 2 terminals. They are directly connected to the source of the power MOSFET. The Rdson is 25m max per output at 25C. Its value increases up to 40m at 150C junction temperature. These are the device input pins, which directly control their associated output. The thresholds are CMOS compatible. When the input is in low state, the associated output MOSFET is off. When input is high, the MOSFET is turned on and the load is activated. When both inputs are low, the device is in standby mode and its supply current is less than 10uA for Vbat up to 14V. for These pins corresponds to a current recopy for each outputs. Their high accuracy permit to allow a precise monitoring of the outputs loads as well as to detect a failed lamp among several lamps. An external resistor must be connected to these pins which can be tied to a microcontroller A/D for analog measurements These pins are the channel 1 and 2 status. Their internal structure is an open drain with an internal clamp at 6V. An external pull up connected to the 5V is needed. When the device is in normal condition the status is high. If open load or overtemperature occurs on one channel, the associated output status will be pulled low.
