TI TPS12111LQDGXRQ1

The TPS1211-Q1 family is a 45-Vi, smart high-side driver with protection and diagnostics. With wide operating voltage range of 3.5 V - 40 V, the device is suitable for 12-V system designs. The device has a strong 3.7-A peak source (PU) and 4-A peak sink (PD) gate driver that enables power switching using parallel FETs in high-current system designs. Use INP as the gate driver control input. The device has accurate current sensing (±2% at 30 mV) output (IMON) enabling system designs for energy management. The device has integrated two-level overcurrent protection with FLT_I output with complete adjustability of thresholds and response time. Auto-retry and latch-off fault behavior can be configured. The device features remote overtemperature protection with FLT_T output. The TPS12111-Q1 integrates a precharge driver (G) with control input (INP_G). This features enables designs that must drive large capacitive loads. In shutdown mode (EN/UVLO < 0.3 V), the controller draws a total shutdown current of 0.9 μA (typical). The TPS1211-Q1 is available in a 19-pin VSSOP package with a pin removed between adjacent high voltage and low voltage pins, providing 0.8 - mm clearance.
