The TPS43331-Q1 is a multi-rail output voltage regulator, with two synchronous switch mode controllers and two linear regulators. In addition, there is a reverse protected high side switch and voltage supervisor for monitoring the standby regulator and input voltage. The regulator outputs and high side switch are controlled either by discrete inputs for certain outputs and serial interface using the I2C configuration for outputs not controlled by discrete inputs.
The standby linear regulator (VSTBY) is high voltage tolerant and can be connected directly to the vehicle battery, the quiescent current is typically 65 µA to maintain a regulated output with light loads.
