MSL3164BT-R

Overview

The MSL3164BT-R is a 16-channel linear LED driver IC from Microchip Technology's Adaptive SourcePower series. It operates with a supply voltage of 5V to 5.5V and delivers up to 100mA per channel. The device supports PWM dimming at frequencies up to 20MHz and is housed in a 40-TQFN (6x6) package. Designed for white and RGB LED applications, it functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates 16 independent linear output channels for precise current control
• Supports high-frequency PWM dimming for flicker-free performance
• Utilizes Adaptive SourcePower technology for efficient power management

Applications

• White LED backlighting systems
• RGB LED lighting arrays
• Adaptive power control circuits

Procurement Notes

Verify component authenticity through authorized Microchip distributors or certified partners. Confirm the specific suffix indicates reel packaging. Check for end-of-life status as availability may be limited. Ensure compatibility with existing PCB footprints and thermal requirements before procurement.

Selection Notes

Select this component for designs requiring multiple synchronized LED channels with linear regulation. Consider the 40-TQFN package size for space-constrained layouts. Evaluate thermal dissipation needs given the linear topology. Verify that the 5V supply rail aligns with system power architecture.

Part Context

This part belongs to the MSL3164 family of LED drivers. It shares functional similarities with other members like the MSL3164BT but differs in packaging configuration. The R suffix typically denotes tape-and-reel packaging suitable for automated assembly processes.

Replacement Considerations

Direct substitutes include other parts within the MSL3164 family such as the MSL3164BT. Verify pinout compatibility and electrical specifications before substitution. Cross-reference datasheets to ensure equivalent channel counts and current capabilities.
