MSL2161DQ

Overview

The MSL2161DQ is a 16-channel linear LED driver IC from Microchip Technology, designed for white and RGB LED applications. It operates on a 12V supply with a range of 10.8V to 13.2V. The device features PWM dimming at 20MHz and utilizes Adaptive SourcePower technology for efficiency. It is housed in a 64-TQFN (9x9) package with an exposed pad. Operating temperatures span -40°C to +105°C. It supports I2C serial interface for frame-by-frame control.

Feature Summary

Supports 16 independent output channels for linear PWM dimming
Integrates Adaptive SourcePower technology for high efficiency
Features low quiescent current consumption
Provides wide operating temperature range capability

Applications

LED backlighting systems
General LED lighting solutions
White and RGB LED string drivers

Procurement Notes

Verify component authenticity through authorized Microchip distributors or certified partners. Confirm the specific suffix 'DQ' matches the required 64-TQFN package variant. Check for end-of-life status as some listings indicate discontinuation. Ensure environmental compliance documentation aligns with project requirements before finalizing procurement decisions.

Selection Notes

Select this component when 16-channel linear control is required for LED strings. It is suitable for designs needing I2C interface integration. Consider the 12V input voltage constraint during power budgeting. Evaluate thermal performance within the TQFN-64 package constraints for high-density PCB layouts requiring surface mount installation.

Part Context

This part belongs to the MSL2160/MSL2161 family of LED drivers. While the MSL2160 uses a 20MHz SPI bus, the MSL2161 specifically offers a 1MHz I2C serial interface. Both support video frame-by-frame LED string control. The MSL2161DQ represents the automotive-grade version of this series.

Replacement Considerations

The MSL2160DQ is a related variant but differs by using SPI instead of I2C. Verify interface compatibility before substitution. No other direct public substitute part numbers are confirmed for this specific model.
