Overview
The A6285EETTR-T is a linear LED driver IC manufactured by Allegro MicroSystems. It features a shift register topology with sixteen independent outputs, each capable of delivering up to 80mA. The device operates on a supply voltage ranging from 3V to 5.5V and supports an internal switching frequency of 30MHz. Designed for surface mount installation, it utilizes a 32-VFQFN package with exposed pad (5x5mm). The component functions within an ambient temperature range of -40°C to 85°C.
Feature Summary
- Integrates sixteen individually controllable linear output channels for precise current regulation.
- Utilizes a serial shift register interface to manage output states efficiently.
- Incorporates internal power switches to simplify circuit design and reduce external component count.
Applications
- LED backlighting systems
- General illumination arrays
Procurement Notes
Verify the specific suffix EETTR-T against official manufacturer documentation to confirm the tape and reel packaging configuration. Confirm that the 32-QFN(5x5) footprint matches the target PCB layout requirements. Ensure thermal management strategies account for the exposed pad design during integration.
Selection Notes
Select this component when a high channel count is required for uniform LED array control. The linear topology suits applications where noise immunity is prioritized over maximum efficiency. Verify that the 5.5V maximum supply voltage aligns with the system power rails before finalizing the design.
Part Context
This part belongs to the A6285 series of LED drivers from Allegro MicroSystems. The series focuses on providing multi-channel solutions for display and lighting applications. The specific model integrates standard linear drive capabilities within a compact form factor suitable for space-constrained electronic assemblies.
