A2982ELW

Overview

The A2982ELW is an eight-channel source driver manufactured by Allegro MicroSystems. It features a bipolar output configuration with NPN and PNP transistors, providing a maximum continuous collector current of 500 mA per channel. The device operates within a load voltage range of 5V to 50V and supports a maximum collector-emitter voltage (Vceo) of 50V. It utilizes a non-inverting open/switch interface for control. The component is housed in a 20-pin SOIC W surface-mount package with dimensions of 12.8mm length and 2.35mm height. It functions within an operating temperature range of -40°C to 85°C.

Feature Summary

• Eight-channel bipolar source driver architecture integrating NPN and PNP outputs on a single chip
• Non-inverting switch interface for direct logic control without signal inversion
• High-side output configuration suitable for sourcing current to loads
• Integrated transient protection mechanisms for circuit robustness

Applications

• General power switching applications requiring high-side drive

Procurement Notes

Verify the specific suffix ELW against current manufacturer catalogs as this part number may be discontinued or superseded. Confirm RoHS compliance status, as historical data indicates non-compliance for certain variants. Ensure the procurement source provides valid datasheets matching the 20-SOIC package and bipolar output specifications. Cross-reference the manufacturer part number with official Allegro MicroSystems documentation to avoid counterfeit components.

Selection Notes

Select this component when an eight-channel bipolar source driver is required for high-side switching applications. It is appropriate for designs needing non-inverting control signals and operation up to 50V load voltage. Consider the 20-SOIC package constraints and the -40°C to 85°C operating temperature range during thermal design. Verify that the 500mA current rating meets the specific load requirements of the application.

Part Context
