TPS1HTC30-Q1 is a single-channel, smart high-side switch, with integrated NMOS power FET and charge pump, designed to meet the requirements of 24V and 48V automotive battery systems. The low RON minimizes device power dissipation driving load current up to 6A DC, and the 60V DC operating range improves system robustness. The TPS1HTC30C-Q1 supports a maximum voltage rating of 70V DC.

The device integrates protection features such as thermal shutdown, output clamp, and current limit to improve system robustness during faults such as short circuit. The device implements an adjustable current limit to improve the reliability of the system by reducing inrush current when driving capacitive loads. The device also provides an accurate current sense that allows for improved load diagnostics such as overload and open-load detection, enabling better predictive maintenance. The device is available in a small 14-pin leaded package with 0.65mm pitch, minimizing the PCB footprint.
