TPS4816-Q1 is a family of low IQ smart high side drivers with protection and diagnostics. With wide operating voltage range of 3.5V to 95V, (100V absolute-maximum rating) the device is suitable for 12V, 24V, and 48V automotive system designs.
The device has a strong 0.5A peak source and 2A peak sink 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.
It also 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 1µA at 48V supply input.
The device has accurate bi-directional current sensing (±2%) output (IMON, I_DIR) with adjustable I2t based overcurrent and short circuit protection (±5%) using an external RSNS resistor and FLT indication. Auto-retry and latch-off fault behavior can be configured. The device also has NTC based temperature sensing (TMP) and monitoring output (ITMPO) output for overtemperature detection of external FETs.
TPS4816-Q1 is available in a 23-pin VQFN package.
