Overview
The A80601KESJSR is an LED lighting driver IC from Allegro MicroSystems, designed as a wide input voltage range boost/SEPIC controller with integrated LED drivers. It features four output channels capable of delivering up to 210 mA per channel. The device operates within a supply voltage range of 4.5 V to 40 V and supports switching frequencies between 260 kHz and 2.3 MHz. It utilizes a 24-WFQFN package with exposed pad for surface mount installation. The component is qualified to AEC-Q100 standards and functions reliably across temperatures from -40°C to +125°C.
Feature Summary
- Supports Boost and SEPIC topologies for flexible input voltage handling
- Integrates analog and PWM dimming control capabilities
- Includes four independent high-side LED driver outputs
- AEC-Q100 qualified for automotive reliability requirements
Applications
- Automotive exterior lighting systems
- Automotive interior ambient lighting
- General LED backlighting applications
Procurement Notes
Verify the specific suffix 'KESJSR' against the official datasheet to confirm package type, tape-and-reel specifications, and moisture sensitivity level. Ensure compatibility with the target PCB footprint for the 24-WFQFN package. Confirm that the required output current and input voltage ranges align with the system design before procurement.
Selection Notes
Select this component when a four-channel LED driver with integrated power switches is required for non-isolated applications. It is suitable for designs needing wide input voltage tolerance and support for both analog and PWM dimming methods. Consider alternative models in the A8060x series if different channel counts or current ratings are needed.
Part Context
This part belongs to the A80601 family of high-power LED drivers from Allegro MicroSystems. These devices are engineered for automotive and industrial lighting where robust performance and compact integration are critical. The family shares common architectural features but varies in output count and current capacity.
Replacement Considerations
Check for direct substitutes such as other variants within the A80601/A80602/A80605 families if pinout and electrical parameters match. Verify functional equivalence regarding topology support and dimming interfaces before substitution.
