A2982SLW-T – ALLEGRO

The A2982SLW-T, manufactured by Allegro MicroSystems, is a monolithic full-bridge power driver integrated circuit fabricated using bipolar technology. It is designed for driving inductive loads such as relays, solenoids, and stepper motors. The device features a single full-bridge output configuration (1:1) housed in a 20-pin Small Outline Integrated Circuit (SOIC) package, suitable for surface mount assembly. The A2982SLW-T incorporates internal clamp diodes to protect the outputs from inductive kickback voltages generated during switching. The bipolar construction facilitates robust operation and efficient power handling within specified voltage and current limits, typically up to 50V and 1A respectively, depending on thermal management and application conditions. It requires external logic inputs to control the bridge configuration and direction of current flow through the load.
