Description
AI
TPS1HTC30-Q1 is a single-channel, smart high-side switch, with integrated NMOS power FET and charge pump, designed to meet the requirements of 24-V automotive battery systems. The low R ON(30 mΩ) minimizes device power dissipation driving a wide range of output load current up to 6-A DC, and the 60-V DC operating range improves system robustness.
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. TPS1HTC30-Q1 implements an adjustable 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 also provides an accurate load current sense that allows for improved load diagnostics such as overload and open-load detection enabling better predictive maintenance.
TPS1HTC30-Q1 is available in a small 14-pin, 4.40-mm × 5.0-mm HTSSOP leaded package with 0.65-mm pin pitch minimizing the PCB footprint.
