TPS2HC08-Q1 is a dual-channel, smart high-side switch, with integrated NMOS power FETs and charge pump, designed to meet the requirements of 12V automotive battery systems. The low RON (9.4mΩ) minimizes device power dissipation when driving a wide range of output load current up to 7.5A DC when both channels are enabled or 10A DC when only one channel is enabled.

The device integrates protection features such as thermal shutdown, output clamp, and current limit. TPS2HC08-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 adjustable current limit can be adjusted from (7.5A to 30A) using an external resistor on the ILIM pin. The devices offers current limit settings with and without thermal regulation. The thermal regulated current limit can be useful when charging large capacitors at start-up. The current limit setting without thermal regulation is useful for loads such motor stall currents or bulb loads.

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. TPS2HC08-Q1 is available in a 11-pin, 2.2mm × 3.6mm QFN leaded package with 0.55mm pin pitch minimizing the PCB footprint.
