TPS2HC08-Q1 is a dual-channel, smart high-side switch, with integrated NMOS power FETs and charge pump, designed for 12V automotive battery systems. The low on-resistance (9.5mΩ) minimizes device power dissipation when driving 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 25A) using an external resistor on the ILIM pin. The device offers both thermal-regulated current limiting for capacitive loads at startup and non-regulated current limiting for motor inrush or bulb applications.

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. TPS2HC08-Q1 is available in a 11-pin, 2.2mm × 3.6mmVQFN-HR wettable-flank package with 0.55mm pitch, minimizing the PCB footprint.
