Overview
The MSL2162DQ-R is a linear LED driver IC from Microchip Technology, designed for white and RGB LED lighting applications. It features 16 independent output channels with PWM dimming capabilities. The device operates on a 12 V supply voltage and is housed in a 64-TQFN (9x9 mm) package with an exposed pad. It supports surface-mount installation and functions within a temperature range of -40°C to +85°C. The maximum power dissipation is 2.1 W, with a maximum supply current of 30 mA.
Feature Summary
- Provides 16 independent linear output channels for precise LED current control
- Supports high-resolution PWM dimming for smooth brightness adjustment
- Integrated thermal protection to safeguard against overheating during operation
Applications
- White LED backlighting systems
- RGB LED color mixing fixtures
- General solid-state lighting drivers
Procurement Notes
Verify component authenticity through authorized distributors or certified suppliers due to potential counterfeit risks. Confirm the specific suffix 'R' indicates reel packaging if required by assembly equipment. Check RoHS compliance status as indicated in official documentation. Ensure the 64-TQFN footprint matches the PCB design layout precisely before procurement.
Selection Notes
Select this component for designs requiring multiple independently controlled LED strings without complex switching regulators. The linear topology simplifies circuit design but requires attention to thermal management due to power dissipation limits. Ensure the input voltage aligns with the 12 V nominal requirement. Consider the TQFN package size constraints when determining board space allocation.
Part Context
This part belongs to the MSL21xx series of LED drivers from Microchip Technology, formerly Atmel. These devices are engineered for cost-effective and reliable LED illumination solutions. The series typically offers integrated protection features and simplified control interfaces suitable for consumer and commercial lighting products.
Replacement Considerations
Consult official Microchip documentation for direct pin-to-pin replacements. Verify compatibility regarding output channel count, package dimensions, and electrical specifications before substituting.
