MIC2845A-PGYMT-TR

LED Driver IC Overview

The MIC2845A-PGYMT-TR is a high-efficiency six-channel linear white LED driver from Microchip Technology. It operates with an input voltage range of 3 V to 5.5 V and provides a regulated output voltage of 3 V. The device delivers up to 0.5 A output current across its channels. Key features include Digital Analog Modulation (DAM), ultra-fast PWM control, and dual low IQ LDOs for system power management. It is housed in a 14-pin UFQFN package with an exposed pad.

LED Driver IC Feature Summary

• Integrates six independent linear channels for driving white LEDs with high efficiency.
• Supports both Digital Analog Modulation (DAM) and ultra-fast Pulse Width Modulation (PWM) dimming methods.
• Includes dual low quiescent current Low Dropout Regulators (LDOs) for auxiliary power supply needs.
• Designed for compact surface-mount applications using a 14-pin UFQFN package.

LED Driver IC Applications

• Mobile device display backlighting
• Camera flash illumination systems
• Portable electronic device lighting

LED Driver IC Procurement Notes

Verify component status carefully as the MIC2845A-PGYMT-TR is listed as obsolete by major distributors. Confirm availability through authorized channels or secondary markets if sourcing is required. Ensure compatibility with existing design specifications before procurement due to potential end-of-life constraints.

LED Driver IC Selection Notes

Select this component for designs requiring multi-channel linear LED driving with integrated power regulation. Consider the 3V to 5.5V input range and 0.5A current capability against load requirements. Evaluate the thermal performance of the 14-pin UFQFN package for the specific application environment.

LED Driver IC Part Context

This part belongs to the MIC2845A series of LED drivers manufactured by Microchip Technology. It is designed specifically for portable electronics where space and efficiency are critical. The PGYMT suffix indicates the specific tape and reel packaging configuration for the 14-TMLF package type.

LED Driver IC Replacement Considerations

As the MIC2845A-PGYMT-TR is marked obsolete, direct substitutes may be limited. Review Microchip's newer LED driver portfolios for functional equivalents. Verify pinout compatibility and electrical parameters when considering alternative components from other manufacturers.
