A6279EA-T

Overview

The A6279EA-T is a linear LED driver IC manufactured by Allegro MicroSystems, designed for high-precision lighting applications. It features 16 independent output channels with an internal shift register for serial data input and PWM dimming control. The device operates on a supply voltage range of 3V to 5.5V and delivers a maximum output current of 75.5mA per channel. Packaged in a 16-pin DIP format, it supports an operating temperature range from -40°C to 85°C.

Feature Summary

Integrates a 16-bit shift register for simplified serial interface control
Provides individual PWM dimming capability for each output channel
Features linear regulation for precise constant current control

Applications

Automotive interior ambient lighting systems
General indicator lighting arrays
Low-power display backlighting modules

Procurement Notes

Verify the package type carefully as the suffix 'EA' denotes a specific DIP configuration distinct from other variants. Confirm end-of-life status and lead times due to potential discontinuation. Ensure compatibility with existing PCB footprints before finalizing procurement decisions.

Selection Notes

Select this component when a low-voltage linear solution with multiple individually addressable outputs is required. It is suitable for designs prioritizing simplicity over efficiency compared to switching regulators. Verify that the thermal dissipation capabilities of the DIP package meet the system's power requirements under maximum load conditions.

Part Context

This part belongs to the A6279 family of linear LED drivers from Allegro MicroSystems. It shares functional similarities with surface-mount variants like the A6279EETTR-T but offers through-hole mounting options. The family is characterized by integrated shift registers and high channel counts for complex lighting topologies.

Replacement Considerations

Direct pin-compatible replacements within the same package may be limited. Consider the A6279EETTR-T if redesigning for surface mount. Verify electrical parameters against alternative linear drivers from other manufacturers if sourcing is constrained.
