MSL3164BT

Overview

The MSL3164BT is a linear LED driver IC manufactured by Microchip Technology, formerly Atmel. It features sixteen independent output channels designed for driving white and RGB LEDs. The device supports linear pulse-width modulation (PWM) dimming to control brightness levels. Each channel provides a constant current output of 100mA. The component is housed in a 40-pin TQFN package with dimensions of 6x6 mm.

Feature Summary

• Integrates sixteen independent output channels for simultaneous LED control
• Supports linear PWM dimming functionality for precise brightness adjustment
• Provides constant current drive capability at 100mA per channel

Applications

• White and RGB LED lighting systems
• LED backlighting drivers
• General-purpose LED matrix control

Procurement Notes

Verify the manufacturer designation as Microchip Technology, which acquired Atmel. Confirm the specific suffix 'BT' indicates the 40-TQFN (6x6) package variant. Ensure compatibility with system voltage requirements and thermal management needs associated with linear regulation. Cross-reference datasheets for pinout accuracy before integration.

Selection Notes

Select this component when a multi-channel solution for white and RGB LEDs is required. The linear architecture suits applications where simple control interfaces are preferred over complex digital protocols. Evaluate thermal dissipation capabilities due to the linear regulation method. Ensure the 100mA per channel rating meets the load requirements of the target LED configuration.

Part Context

This part belongs to the MSL3164 series of LED drivers. The series is characterized by its ability to handle multiple outputs for color mixing and brightness control. The transition from Atmel to Microchip Technology affects branding but not the technical specifications of the silicon.

Replacement Considerations

The MSL3164BT-R is a related variant with reel packaging. Verify functional equivalence if substituting based on packaging differences.
