The TPS4811x-Q1 family is a 100-V smart high side driver with protection and diagnostics. With wide operating voltage range of 3.5 V – 80 V, the device is suitable for 12-V, 24-V, and 48-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. MOSFET slew rate control (ON and OFF) is possible by placing external R-C components.

The device has accurate current sensing (±2 % at 30-mV V_SNS) output (IMON) enabling systems 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 enabling robust system protection.

TPS48110-Q1 has an accurate overvoltage protection (< ±2 %), providing robust load protection.

The TPS48111-Q1 integrates a pre-charge driver (G) with control input (INP_G). This feature enables system designs that need to drive large capacitive loads by pre-charging first and then turning ON the main power FETs.

TPS4811x-Q1 has an accurate undervoltage protection (< ±2 %) using EN/UVLO pin. Pull EN/UVLO low (< 0.3 V) to turn OFF the device and enter into shutdown state. In shutdown mode, the controller draws a total shutdown current of 1.6 µA at 48-V supply input.
