Description：

The TPS1211-Q1 family is a 45-V, smart high-sidedriver with protection and diagnostics. With wideoperating voltage range of 3.5 V–40 V, the device issuitable for 12-V system designs.The device has a strong 3.7-A peak source (PU) and4-A peak sink (PD) gate driver that enables powerswitching using parallel FETs in high-current systemdesigns. Use INP as the gate driver control input.The device has accurate current sensing (±2% at30 mV) output (IMON) enabling system designsfor energy management. The device has integratedtwo-level overcurrent protection with FLT_I outputwith complete adjustability of thresholds andresponse time. Auto-retry and latch-off fault behaviorcan be configured. The device features remoteovertemperature protection with FLT_T output.The TPS12111-Q1 integrates a precharge driver (G)with control input (INP_G). This features enablesdesigns that must drive large capacitive loads. Inshutdown mode (EN/UVLO < 0.3 V), the controllerdraws a total shutdown current of 0.9 µA (typical).The TPS1211-Q1 is available in a 19-pin VSSOPpackage with a pin removed between adjacent highvoltage and low voltage pins, providing 0.8-mmclearance.
