The TPS4H82H85-Q1 device is fully protected dual-channel smart high-side switch with two integrated 85mΩ NMOS power FETs, intended for 24V and 48V automotive systems. The low RON minimizes the device power dissipation when driving a wide range of output load current up to 2.2A when both channels are enabled or 3A when only one channel is enabled. Protection and diagnostic features include accurate current sense, selectable current limit levels, OFF-state open-load, short-to-battery detection, output clamp, and thermal shutdown.

The device provides an accurate load current sense that allows for improved load diagnostics such as overload and open-load detection, which enables better predictive maintenance, without further calibration. The device also implements a selectable current limiting circuit that improves the reliability of the system by reducing inrush current when driving large capacitive loads and minimizing overload current. The TPS4H82H85-Q1 device can be used as a high-side power switch for a wide variety of resistive, inductive, and capacitive loads, including low-wattage bulbs, LEDs, relays, solenoids, and heaters.
