Overview
The A6216KLPTR-T is an automotive-grade buck LED driver IC from Allegro MicroSystems. It features a wide input voltage range of 4.5V to 60V and supports PWM dimming for precise current control. The device integrates high-side and low-side power switches, enabling efficient constant current regulation for single-channel LED applications. It operates within a junction temperature range of -40°C to +150°C and is housed in a thermally enhanced 16-lead LP-16 package.
Feature Summary
- Integrated high-side and low-side power switches for efficient buck topology
- Supports analog and PWM dimming inputs for flexible brightness control
- Built-in protection mechanisms including overvoltage, overtemperature, and open-load detection
Applications
- Automotive exterior lighting systems
- LED headlamp modules
- Fog lamp drivers
- Daytime running light circuits
Procurement Notes
Verify the specific suffix and tape-and-reel quantity against the manufacturer's latest datasheet before ordering. Confirm that the LP-16 package dimensions match your PCB footprint requirements. Ensure supply chain sources provide valid traceability documentation for automotive grade components.
Selection Notes
Select this component when a single-channel, high-voltage buck driver is required for automotive LED applications. Consider the 60V maximum input limit and the integrated switch current capabilities. Evaluate thermal management needs due to the high operating temperature rating and power dissipation characteristics inherent to the buck topology.
Part Context
This part belongs to the A6216 family of automotive LED drivers designed for robust performance in harsh environments. It complements other Allegro solutions by offering a simplified design for single-string LED loads while maintaining high efficiency and reliability standards required for vehicle safety lighting systems.
Replacement Considerations
Consult official Allegro MicroSystems documentation for qualified pin-to-pin or functional replacements. Verify compatibility with existing board layouts and thermal constraints when substituting.
