TPS4812-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 absmax the device is suitable for 12V, 24V and 48V automotive system designs.
It has two integrated gate drives with 0.5A source and 2A sink (GATE) and 100µA source and 0.39A sink (G). With LPM Low, the low power path is kept ON and the main FETs are turned OFF with IQ of 20µA (typ). Auto Load wakeup threshold adjusted using RBYPASS resistor placed across DRN and CS2–. IQ reduces to 1µA (typ) with EN/UVLO low.
The device has accurate bi-directional current sensing (±2%) output (IMON, I_DIR) with adjustable I2t based overcurrent and short circuit protection 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.
The TPS4812-Q1 is available in 23-pin VQFN package.
