A6276SLWTR

Overview

The A6276SLWTR is a linear LED driver IC manufactured by Allegro MicroSystems, housed in a 24-SOIC surface-mount package. It features 16 outputs with an internal shift register topology and supports PWM dimming. The device operates on a supply voltage range of 4.5V to 5.5V, delivering up to 75.5mA per output channel at a maximum output voltage of 4V. It functions within a temperature range of -20°C to +85°C and includes internal switches for direct load control.

Feature Summary

Integrates a 16-output linear driver with an internal serial shift register for simplified interface control.
Supports PWM dimming functionality for precise brightness adjustment across multiple channels.
Features internal power switches to directly drive LED loads without external components.

Applications

LED display segment drivers
General-purpose LED lighting arrays
Industrial indicator panels

Procurement Notes

Verify component status as the A6276 series is listed as obsolete or end-of-life in current distributor databases. Confirm RoHS compliance variations between tape-and-reel and tube packaging variants. Ensure replacement strategies are evaluated due to potential supply chain discontinuation risks associated with legacy part numbers.

Selection Notes

Select this component for applications requiring fixed-current linear regulation with serial input control. Verify that the 5.5V maximum supply voltage aligns with system power rails. Consider thermal dissipation requirements given the linear topology and 75.5mA per-channel capability in the SOIC-24 package.

Part Context

Part of the A6276 family of LED drivers from Allegro MicroSystems, designed for multi-segment display and lighting applications. The SLW suffix denotes the specific SOIC wide package variant with tape-and-reel delivery format.

Replacement Considerations

Consult manufacturer documentation for direct pin-compatible successors. Evaluate alternative Allegro LED drivers with similar 16-channel configurations if availability is critical.
