Achieve reliable output power protection
High-accuracy current sensing
Accurate current sensing enables real-time monitoring of system loads through open load detection without calibration and eliminates the need for additional sensing components.
Adjustable current limit for targeted protection
Our high-side switches help protect against high inrush current, overload and short-circuit conditions. Adjustable current limit reduces PCB traces and connector sizes to lower your system costs.
Robust, qualified solutions
Our devices are tested against the rigorous requirements of industry standards, including AEC-Q100, ISO-7637 and IEC-61000.
