The TPS4811x-Q1 family is a 100V smart high side driver with protection and diagnostics. With wide operating voltage range from 3.5V to 80V, the device is an excellent choice for 12V, 24V, and 48V 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%) 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 times. Auto-retry and latch-off fault behavior can be configured. The device features remote overtemperature protection with FLT_T output.
The TPS48111Q1 integrates a pre-charge driver (G) with control input (INP_G). This features enables designs that must drive large capacitive loads. In shutdown mode, the controller draws a total shutdown current of 1.6µA at 48V supply input.
The TPS4811x-Q1 is available in a 19-pin VSSOP package with a pin removed between adjacent high voltage and low voltage pins, providing 0.8mm clearance.
