The TPS1HC120-Q1 is a fully protected high-side switch, with integrated NMOS power FET and charge pump, designed to meet the requirements of 12V automotive systems. The low RON (120mΩ typical) minimizes the device power dissipation when driving a wide range of output load current up to 1.5A.
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 device implements a selectable high-accuracy current limit that improves the reliability of the system by reducing inrush current when driving large capacitive loads. For the A/B variants, the device also provides an accurate current sense that allows for improved load diagnostics such as overload and open-load detection. Low logic high threshold, VIH, of 1.5V on the input pins allow use of MCUs down to 1.8V.
The TPS1HC120-Q1 can be used to drive a wide variety of resistive, inductive, and capacitive loads, including ADAS cameras, LEDs, relays, solenoids, and heaters. The device is available in a 8-pin, ultra-small form-factor 2.1mm × 1.6mm SOT package with 0.5mm pin pitch, minimizing the PCB footprint.
