A6841SLW-20-T

Overview

The A6841SLW-20-T is a bipolar power driver manufactured by Allegro MicroSystems, designed for driving multiple loads from a single input. It features an 8-channel output configuration with a 1:8 input-to-output ratio. The device operates within a supply voltage range of 3V to 5.5V and supports load voltages up to 50V. Each channel provides a maximum output current of 500mA. It utilizes non-inverting parallel or serial interfaces and is housed in a 20-SOIC surface-mount package.

Feature Summary

• Provides eight independent low-side outputs controlled by a single input signal
• Supports both parallel and serial interface modes for flexible system integration
• Features bipolar output configuration suitable for driving various load types

Applications

• Stepper motor drive systems requiring multi-phase control
• Solenoid valve arrays in industrial automation equipment
• High-density LED lighting matrix drivers
• Relay bank switching applications

Procurement Notes

Verify the exact suffix designation during procurement, as variations such as SLWTR indicate specific tape-and-reel packaging configurations. Confirm that the component status aligns with project requirements, noting potential end-of-life constraints for this specific part number. Ensure compatibility with existing PCB footprints for the 20-SOIC package before finalizing orders.

Selection Notes

Select this component when a single control line must manage multiple simultaneous loads efficiently. It is appropriate for designs requiring moderate current handling per channel without complex external circuitry. Consider the operating temperature range and voltage limits to ensure they match the target application environment. Evaluate interface requirements to determine if parallel or serial communication best suits the system architecture.

Part Context

This part belongs to the A6841 series of power drivers from Allegro MicroSystems. The series is characterized by its ability to simplify multi-load control architectures. The specific model indicates a standard commercial grade device in a SOIC package, distinct from automotive-grade variants which may carry different suffixes or enhanced thermal specifications.

Replacement Considerations

Direct substitutes include other Allegro A6841 variants with compatible pinouts and electrical characteristics. Verify that any replacement maintains the same 20-SOIC footprint and 1:8 ratio functionality. Cross-reference datasheets to ensure equivalent voltage and current ratings are met.
