Automotive, 100V low-Iq dual high-side driver with short circuit protection and diagnostics

The TPS48100-Q1 is a 100V low IQ smart

high side driver with protection and diagnostics. With wide operating voltage range from

3.5V to 95V, the device is an excellent choice for 12V, 24V, and 48V system designs. The

device can withstand and protect the loads from negative supply voltages down to –65V.

The device has two strong 2A (source and 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. Configure the auto-retry and latch-off fault behavior. Complete current sensing

either by an external sense resistor or by MOSFET VDS sensing. High side or low side current

sense resistor configuration is possible by using CSSEL pin input. The device also features

diagnosis of the internal short circuit comparator using external control on SCPTEST

input.

A low quiescent current (35µA, typical) in operation enables always ON system designs. Quiescent current reduces to 1µA (typical) with EN/UVLO low.

The TPS48100-Q1 is available in a 19-pin VSSOP package.
