MSL2160DQ

Overview

The MSL2160DQ is a 16-string LED driver manufactured by Microchip Technology, housed in a 64-TQFN (9x9) package. It supports linear dimming with a maximum output current of 350mA per channel and operates on a 20MHz frequency. The device accepts PWM dimming signals and functions within a supply voltage range of 10.8V to 13.2V. It is designed for backlight and lighting applications, operating reliably across a temperature range of -40°C to +105°C.

Feature Summary

• Supports 16 independent LED strings with adaptive configuration capabilities
• Integrates EEPROM for non-volatile data storage and SPI/I2C/SMBus serial interface
• Enables precise linear dimming control alongside PWM dimming input

Applications

• LED backlighting systems
• General solid-state lighting fixtures
• RGB LED color mixing arrays

Procurement Notes

Verify the specific suffix designation against official Microchip documentation to confirm pinout and functional variations. Ensure the selected variant matches the required thermal management specifications for the intended enclosure. Cross-reference the datasheet revision date to validate compatibility with existing design files and regulatory compliance requirements.

Selection Notes

Select this component when designing high-density LED arrays requiring individual string control. The integrated EEPROM simplifies calibration data storage, reducing external memory needs. Consider the 64-TQFN package size for PCB layout constraints and ensure adequate thermal dissipation paths are implemented for operation at elevated ambient temperatures.

Part Context

This part belongs to the Atmel-derived MSL2160/MSL2161 family of white and RGB LED drivers. These components utilize adaptive configuration algorithms to optimize performance across varying LED loads. The series is characterized by its robust serial communication interfaces and support for complex dimming profiles in professional lighting environments.

Replacement Considerations

Consult official substitution lists for variants such as MSL2160DQ-R or MSL2161 equivalents. Verify that any alternative maintains identical pin assignments and electrical characteristics to avoid redesigning the host circuit board or firmware.
