Overview
The A2982SLWTR-T is an eight-channel bipolar power driver manufactured by Allegro MicroSystems. It operates with a load voltage range of 5V to 50V and provides a maximum output current of 500mA per channel. The device utilizes a non-inverting open/switch interface and features high-side output configuration within a 20-SOIC surface-mount package. It functions without a separate supply voltage requirement and supports an ambient operating temperature range from -20°C to 85°C.
Feature Summary
- Integrates eight independent high-side bipolar output channels for simultaneous load control
- Operates directly from load voltage sources between 5V and 50V without auxiliary supply
- Provides non-inverting logic interface for straightforward digital signal integration
Applications
- General purpose load switching in industrial equipment
- High-side drive applications for resistive or inductive loads
- Automotive accessory control circuits
Procurement Notes
Verify component status as Not Recommended for New Designs (NRND) via official Product Change Notification documents before finalizing designs. Confirm RoHS3 compliance and Moisture Sensitivity Level 3 requirements during assembly planning. Ensure the specific suffix matches the required tape-and-reel packaging specifications.
Selection Notes
Select this component when eight isolated high-side outputs are required within a single package. Verify that the 500mA continuous current rating meets load demands. Consider the 20-SOIC thermal performance for the intended enclosure environment. Check compatibility with non-inverting control signals and ensure the 5V-50V load voltage range aligns with system power rails.
Part Context
This part belongs to the A2982 series of power drivers, designed for general-purpose switching applications. It serves as a surface-mount alternative to through-hole variants like the A2982SLW. The device integrates protection features typical of Allegro's bipolar driver family, offering a compact solution for multi-channel load management in space-constrained designs.
Replacement Considerations
The A2982ELWTR-T is listed as a discontinued direct replacement option. Verify functional equivalence and updated environmental compliance status against current design requirements.
