MSL3167GU-R

Overview

The MSL3167GU-R is an LED driver IC featuring 16 output channels with linear PWM dimming capability. Each channel provides a constant current of 30mA. The device operates within a supply voltage range of 4.75V to 5.5V and supports an operating temperature range from -40°C to +85°C. It is housed in a compact 32-SOP package.

Feature Summary

• Integrates 16 independent output channels for simultaneous LED control
• Supports linear pulse-width modulation (PWM) dimming for brightness adjustment
• Delivers consistent 30mA output current per channel

Applications

• LED backlighting systems
• General LED lighting fixtures
• Display illumination modules

Procurement Notes

Verify the exact suffix 'GU-R' against official Microchip documentation to confirm the specific tape-and-reel packaging variant. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as regulatory status may vary by production batch. Ensure the 32-SOP package footprint matches your PCB design requirements before procurement.

Selection Notes

Select this component when a high-channel-count driver with integrated linear PWM dimming is required. It is suitable for designs needing uniform current distribution across multiple LEDs without external transistors. Consider the 32-SOP package size constraints and the 5V nominal supply requirement during circuit architecture planning.

Part Context

This part belongs to the Microchip MSL316x series of LED drivers. These components are designed for applications requiring multiple synchronized outputs. The MSL3167GU-R specifically offers 16 channels, distinguishing it from other variants in the family that may offer different channel counts or packaging options.

Replacement Considerations

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