SLUUCV7 December 2023 TPS1213-Q1
The TPS1213-Q1 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 an excellent choice for 12-V system designs. The device can withstand and protect the loads from negative supply voltages down to –40 V. The device has integrated two gate drives with 1.69-A src/2-A sink capacity to drive MOSFETs in the main path and 150-μA src/2-A sink capacity for the low power path.
In the low power mode with LPM = Low, the low power path FET is kept ON and the main FETs are turned OFF. The device consumes low IQ of 35- μA (typ) in this mode. Auto Load wakeup threshold to enter into active state can be adjusted using ISCP/LWU pin. IQ reduces to 1-μA (typ) with EN/ UVLO low.
The device provides adjustable short circuit protection using MOSFET VDS sensing or by using an external RSNS resistor. Auto-retry and latch-off fault behavior can be configured. The device also features diagnosis of the internal short circuit comparator using external control on SCP_TEST input.
