Overview
The MSL3085BT-R is an LED lighting driver IC manufactured by Microchip Technology, designed for driving eight strings of white and RGB LEDs. It operates within a supply voltage range of 12 V to 12 V and supports a maximum power dissipation of 2.1 W. The device features eight output channels with a maximum supply current of 25 mA. It is housed in a TQFN-40 package (6x6 mm) suitable for surface mount installation. The component functions reliably across an operating temperature range from -40°C to +85°C.
Feature Summary
- Supports linear PWM dimming control for precise brightness adjustment
- Integrates eight independent output channels for multi-string LED configurations
- Designed specifically for white and RGB LED driver applications
Applications
- White LED backlighting systems
- RGB LED color mixing modules
- General LED lighting driver circuits
Procurement Notes
Verify the end-of-life status before procurement, as the manufacturer indicates this component is scheduled for obsolescence. Confirm that the 40-TQFN package dimensions align with existing PCB footprints. Ensure the 12 V input requirement matches the system power architecture. Check for RoHS compliance documentation if required for specific regulatory standards. Validate that the -40°C to +85°C operating range meets environmental constraints.
Selection Notes
Select this component when an eight-channel LED driver with linear PWM capability is required. It is suitable for designs needing a fixed 12 V supply interface. Consider the TQFN-40 package size for space-constrained layouts. Evaluate the 2.1 W power dissipation limit against thermal management capabilities. This IC is appropriate for applications requiring simultaneous control of white and RGB LED strings.
Part Context
The MSL3085BT-R belongs to the Microchip LED driver family, previously associated with Atmel and Micrel brands. It is categorized under PMIC LED drivers. The part number suffix '-R' typically denotes reel packaging. The component serves as a specialized solution for multi-channel LED illumination tasks.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided data. Due to the end-of-life status, alternative sourcing should be verified through official Microchip channels or authorized distributors for last-time buy options.
