The TPS12000-Q1 is a 45V low IQ smart high side driver with protection and diagnostics. With wide operating voltage range of 3.5V–40V, the device is suitable for 12V system designs. The device can withstand and protect the loads from negative supply voltages down to –40V.
It has a strong (2A) gate drive that 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.
Low quiescent current 43µA (typical) in operation enables always ON system designs. Quiescent current reduces to 1.5µA (typical) with EN/UVLO low.
The TPS12000-Q1 is available in a 19-pin VSSOP package.
