A2982ELWTR-T

Overview

The A2982ELWTR-T is an eight-channel bipolar power driver from Allegro Microsystems, housed in a 20-SOIC surface-mount package. It provides high-side switching for loads operating between 5V and 50V with a maximum continuous collector current of 500mA per channel. The device features non-inverting open/switch interfaces and operates within a temperature range of -40°C to 85°C.

Feature Summary

• Integrates eight independent high-side bipolar output channels on a single chip
• Supports direct interface with standard logic inputs via non-inverting configuration
• Designed for robust switching of inductive and resistive loads up to 50V

Applications

• Solenoid valve control systems
• Relay driver circuits
• Lamp and indicator lighting arrays

Procurement Notes

Verify component authenticity through authorized distributors or the manufacturer directly. Confirm RoHS3 compliance status as indicated in official documentation. Check for Not Recommended for New Design (NRND) status updates prior to finalizing procurement plans.

Selection Notes

Select this component when eight isolated high-side outputs are required in a compact SOIC footprint. Ensure load voltage does not exceed 50V and current remains within 500mA limits. Verify thermal management requirements for the specified operating temperature range.

Part Context

This part belongs to the A2982 series of bipolar power drivers. It shares functional similarities with variants like the A2982SLWTR-T but differs in specific electrical ratings and packaging options. The series is designed for general-purpose load switching applications requiring multiple channels.
