MSL2162DQ

Overview

The MSL2162DQ is a 16-channel LED driver IC designed for white and RGB LED applications. It operates on a single 12V supply and features linear PWM dimming with an integrated EEPROM for adaptive control. The device provides 350mA output current per channel and supports up to 20MHz frequency. It is housed in a 64-pin TQFN package, suitable for surface mount installation.

Feature Summary

• Integrates adaptive control capabilities with non-volatile memory for configuration storage
• Supports high-frequency linear PWM dimming for precise brightness regulation
• Provides independent current control across sixteen output channels

Applications

• White LED backlighting systems
• RGB LED lighting arrays
• Automotive interior illumination modules

Procurement Notes

Verify the specific suffix (e.g., DQ vs DQ-R) against official Microchip documentation to confirm packaging type. Confirm lifecycle status as distribution data indicates potential obsolescence or limited availability. Ensure the component meets required RoHS compliance standards for your target market before finalizing procurement.

Selection Notes

Select this component when designing systems requiring independent control of sixteen LED strings from a single 12V rail. It is appropriate for applications needing adaptive brightness management without external microcontroller intervention for basic functions. Consider thermal dissipation requirements due to the linear regulation architecture.

Part Context

This part belongs to the MSL216x series of LED drivers from Microchip Technology. These devices are engineered for complex lighting architectures where individual channel control and memory retention are critical. The series typically targets automotive and high-end consumer lighting sectors.

Replacement Considerations

Consult official Microchip substitution guides for verified alternatives. Cross-reference pinouts and electrical characteristics carefully if considering generic equivalents.
