A2982ELWTR

Overview

The A2982ELWTR is an eight-channel bipolar power driver IC from Allegro MicroSystems, designed for high-current switching applications. It features a maximum continuous collector current of 500 mA per channel and supports load voltages ranging from 5V to 50V. The device utilizes a 20-SOIC surface-mount package with a width of 7.50 mm. It operates within a temperature range of -40°C to 85°C and includes transient protection. The input interface is non-inverting with a 1:1 ratio, and the output configuration provides high-side sourcing capabilities.

Feature Summary

• Eight independent high-side source drivers integrated into a single dual-bipolar architecture
• Non-inverting open/switch interface providing direct control logic compatibility
• Integrated transient voltage protection mechanisms for enhanced circuit reliability

Applications

• General purpose power switching circuits requiring multiple isolated channels
• Industrial load driving systems utilizing bipolar transistor arrays
• Electronic equipment needing high-side current sourcing up to 500mA per line

Procurement Notes

Verify component authenticity through authorized distribution channels due to discontinued status. Confirm RoHS3 compliance for specific tape-and-reel variants. Validate package dimensions against PCB footprint requirements. Ensure thermal management aligns with specified operating temperature limits. Cross-reference datasheet revisions prior to final design integration.

Selection Notes

Select this component when eight independent high-side outputs are required in a compact form factor. Consider the 500mA current limit and 50V voltage rating for load compatibility. Evaluate the 20-SOIC package constraints for assembly processes. Compare against alternative Allegro series devices if automotive qualification or different pin counts are necessary.
