The TPS4HC120-Q1 is an automotive quad-channel, smart high-side switch, with integrated NMOS power FET and charge pump, designed to meet the requirements of 12V automotive battery systems. The low RON (120mΩ) minimizes the device power dissipation when driving a wide range of output load current up to 2A when all four channels are enabled or 2.5A when only one channel is enabled.

The device integrates protection features such as thermal shutdown, output clamp, and current limit. These features improve system robustness during fault events such as short circuit. The TPS4HC120-Q1 implements a selectable current limiting circuit that improves the reliability of the system by reducing inrush current when driving large capacitive loads and minimizing overload current. The device offers 10 selectable current limit settings (0.25A to 5A) based on the external resistor used on the ILIM pin. The device also provides an accurate load current sense that allows for improved load diagnostics such as overload and open-load detection, which enables better predictive maintenance.

The TPS4HC120-Q1 is available in a 28-pin, 7.1mm × 4.9mm HVSSOP leaded package with 0.5mm pin pitch minimizing the PCB footprint.
