A2982SLWTR

Overview

The A2982SLWTR-T is an eight-channel bipolar power driver IC from Allegro MicroSystems, housed in a 20-SOIC package. It provides high-side switching with a maximum output current of 500mA per channel and supports load voltages ranging from 5V to 50V. The device operates within a temperature range of -20°C to 85°C and features non-inverting open/switch interfaces. This component is classified as Not Recommended for New Designs (NRND) and has been superseded by the A2982SLWTR-T variant.

Feature Summary

• Eight independent high-side bipolar output channels
• Integrated transient voltage protection
• Non-inverting logic interface control

Applications

• General purpose load switching
• Industrial equipment power distribution
• Automotive auxiliary systems

Procurement Notes

Verify the specific ordering suffix carefully. The base part number A2982SLWTR indicates a discontinued status. Ensure the procurement order specifies the correct tape-and-reel suffix (e.g., -T) if availability is confirmed through secondary markets. Confirm RoHS compliance status, as older batches may differ from current NRND designations.

Selection Notes

Select this component only for legacy system maintenance or existing designs requiring exact pinout compatibility. Evaluate the A2982SLWTR-T as the primary alternative for new implementations due to updated manufacturing specifications. Consider thermal management requirements given the 500mA per-channel capability in the SOIC package.

Part Context

This integrated circuit belongs to the A2982 series of power drivers designed for robust industrial applications. It serves as a discrete solution for driving multiple loads without complex microcontroller interfacing. The component represents a transition point in Allegro's product lifecycle, moving from standard production to end-of-life status while maintaining supply through designated distributors.

Replacement Considerations

A2982SLWTR-T is the direct replacement.
