Description
General part information
TPS1211-Q1 Series
The TPS1211-Q1 family is a 45V, smart high-side driver with protection and diagnostics. With wide operating voltage range of 3.5V–40V, the device is suitable for 12V system designs.
The device has a strong 3.7A peak source (PU) and 4A 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 30mV) 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.
