1.4 Device Information

The TPS1214-Q1 is part of a family of low IQ smart high side drivers with protection and diagnostics. With wide operating voltage range of 3.5V to 73V, 74V absmax the device is an excellent choice for 12V, 24V and 48V automotive system designs.

The device has two integrated gate drives with 0.5A/2A (GATE) and 100μA/0.39A (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 CS2+ and CS2–. IQ reduces to 1μA (typ) with EN/UVLO low.

The device has accurate current sensing (±2 %) output (IMON) 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.
