Overview
The A6275SA is a linear LED driver IC manufactured by Allegro MicroSystems, designed for high-brightness LED applications. It features an internal shift register topology with eight independent outputs, each capable of delivering up to 75.5mA. The device operates within a supply voltage range of 4.5V to 5.5V and supports output voltages up to 4V. It utilizes PWM dimming capabilities at a frequency of 20MHz. The component is housed in a 16-DIP package (0.300 inch width) and is rated for an ambient operating temperature range of -20°C to 85°C.
Feature Summary
- Integrates an internal shift register for serial data input control of multiple LED channels.
- Provides constant current regulation for high-brightness LED arrays via linear drive topology.
- Supports pulse-width modulation dimming for precise brightness control.
Applications
- High-brightness indicator lighting
- General-purpose LED array illumination
- Consumer electronics backlighting
Procurement Notes
Verify the specific suffix SA against the official datasheet to confirm pinout and thermal characteristics. Confirm RoHS compliance status as indicated in manufacturer documentation. Check for obsolescence notices or lifecycle changes before finalizing design-in decisions. Ensure the DIP-16 footprint matches the target PCB layout requirements.
Selection Notes
Select this component when a multi-channel linear driver with shift register interface is required. Consider the 75.5mA per channel limit and 5.5V maximum supply voltage constraints. Evaluate thermal dissipation needs due to the linear regulation method. Compare against newer Allegro series if automotive qualification or extended temperature ranges are mandatory.
Part Context
This part belongs to the A6275 family of linear LED drivers from Allegro MicroSystems. The family typically includes variants with different packaging options such as SOIC and TSSOP. These devices are generally positioned for cost-effective, high-current LED driving solutions in non-automotive consumer and industrial markets.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with existing circuit designs if considering alternative manufacturers.
