- Adjustable input undervoltage lockout (UVLO)
The TPS1210x-Q1 family is a 45-V, low IQ, smart high side driver with protection and diagnostics. With wide operating voltage range of 3.5 V – 40 V, the device is designed for 12-V system designs. The device can withstand and protect the loads from negative supply voltages down to –40 V.
The device has two strong (2-A) GATE drivers with separate control inputs (INP1, INP2) to drive back-to-back MOSFETs in common source configuration. TPS12100-Q1 has active high control inputs and TPS12101-Q1 has active low control inputs.
The device provides adjustable short-circuit protection. Auto-retry and latch-off fault behavior can be configured. 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 35 µA (typical) in operation enables always ON system designs. Quiescent current reduces to 1.5 µA (typical) with EN/UVLO low.
The TPS1210x-Q1 is available in a 19-pin VSSOP package.
