Overview
The A80606KEVJSR is a multi-output LED driver IC from Allegro MicroSystems, designed for automotive applications. It features six integrated current sinks capable of driving up to 180 mA per channel, with parallel configurations supporting over 1 A total current. The device operates on a single 4.5 V to 40 V supply and supports Boost or SEPIC topologies using external N-MOSFETs. It includes an integrated gate driver and offers analog and PWM dimming capabilities.
Feature Summary
- Integrates six independent current sinks for high-power LED string control
- Supports external N-MOSFET switching via integrated gate driver for Boost/SEPIC topologies
- Provides patent-pending control scheme for high-performance PWM dimming without capacitor啸叫 noise
Applications
- Automotive exterior lighting including DRL and position lamps
- Headlamp Rear Combination Lamps (RCL)
- Heads-Up Displays (HUD)
- Medium-size LCD backlighting
Procurement Notes
Verify the specific suffix 'KEV' indicates the 48-pin QFN package variant distinct from other series members. Confirm AEC-Q100 qualification status for your target automotive grade requirements. Ensure design compatibility with external MOSFET selection given the integrated gate driver specifications. Check moisture sensitivity level handling procedures during assembly.
Selection Notes
Select this component when designing systems requiring six independent LED channels with high current capacity exceeding standard single-channel drivers. The integrated gate driver simplifies layout by eliminating external driver components for power switches. Consider the wide input voltage range for robustness against automotive load dump conditions.
Part Context
This part belongs to the A80606 family of multi-output LED drivers. It shares functional similarities with the A80605 but offers higher output current density and a different package configuration suitable for higher power dissipation needs in automotive exterior and display applications.
Replacement Considerations
A80606KEVJSR-1 is a documented variant within the same family. Verify pinout and electrical parameter equivalence before substitution. Other series members like A80605 differ in output count and current ratings.
