IR3312S

Power Distribution Switches, Load Drivers Overview

The IR3312S is a single-channel high-side power switch manufactured by Infineon Technologies, designed for general-purpose load driving applications. It features an N-channel output configuration housed in a D2PAK surface-mount package with five leads. The device operates within a load voltage range of 6V to 28V and supports a maximum continuous output current of 14A. Key electrical characteristics include a typical on-resistance of 15 milliohms and a non-inverting input interface. Integrated fault protection mechanisms provide adjustable current limiting and overtemperature shutdown capabilities. The component functions without a separate supply voltage requirement and is rated for junction temperatures between -40°C and 150°C.
