1.4 Device Information

The TPS4810x-Q1 family is a 100-V low IQ smart high side driver with protection and diagnostics. With wide operating voltage range of 3 V–80 V, the device is an excellent choice for 12-V, 24-V and 48-V system designs. The device can withstand and protect the loads from negative supply voltages down to –65 V. The device has two strong 2-A (src/sink) gate drivers with separate control inputs (INP1, INP2) to drive back to back MOSFETs in common source configuration. Strong GATE driving enables power switching using parallel MOSFETs in high current system designs.

The device provides adjustable short circuit protection. Auto-retry and latch-off fault behavior can be configured. By using CS+ and CS- pins, current sensing can be done either by an external sense resistor or by MOSFET VDS sensing. High side or low side current sense resistor configuration is possible by using CS_SEL pin input. The device also features diagnosis of the internal short circuit comparator using external control on SCP_TEST input.
