The TPS12130-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 designed for 12V system designs. The device can withstand and protect the loads from negative supply voltages down to –40V.
TPS12130-Q1 has integrated two gate drives with 1.69A source and 2A sink capacity to drive MOSFETs in the main path and 165µA source and 2A 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 35µA (typ) in this mode. Auto load wakeup threshold to enter into active state can be adjusted using ISCP/LWU pin. IQ reduces to 1µA (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.
The TPS12130-Q1 is available in a 19-pin VSSOP package.
