The NCV47822 from onsemi is an Automotive-Grade Dual High Side Switch that has been designed for use in harsh automotive environments. It requires an input voltage of 4.4-40 V and provides an output current of over 10-350 mA. This dual-channel power switch has an adjustable current limit up to 350 V. It features two independent Enable logic inputs, each compatible with 3.3 V logic. This power switch supports a current sense function using a resistor for current adjustment, which allows for diagnosis and overall system protection.

This AEC-Q100 Grade 1-qualified switch has high peak input voltage tolerance capability and benefits from over-current, over-temperature, and reverse bias protection circuitries for enhanced safety. It also features extended diagnostic capabilities in the OFF state with control options via input and output pins. This RoHS-compliant power switch is available in a surface-mount package that measures 4.90 x 6.40 mm and is ideal for audio systems, infotainment systems and active safety systems.
