MIC4801YM

LED Driver IC Overview

The MIC4801YM is a high-efficiency single-channel linear White LED (WLED) driver manufactured by Microchip Technology. It provides a constant output current of 600mA and operates within a supply voltage range of 3V to 5.5V. The device features ultrafast PWM control for dimming applications. It is housed in an 8-pin SOIC package and supports an operating temperature range from -40°C to +125°C.

LED Driver IC Feature Summary

• Ultrafast PWM control capability for precise dimming
• High efficiency linear regulation design
• Constant current output optimized for single WLED

LED Driver IC Applications

• White LED backlighting systems
• Portable electronic device illumination
• Single channel LED driving circuits

LED Driver IC Procurement Notes

Verify the specific suffix 'YM' corresponds to the SOIC-8 tube packaging variant when ordering. Confirm that the required operating temperature range extends to +125°C matches the component specifications. Ensure the input voltage supply remains within the 3V to 5.5V limits to maintain proper constant current regulation. Cross-reference the manufacturer part number with official Microchip documentation to avoid confusion with other series variants.

LED Driver IC Selection Notes

Select this component for applications requiring a simple, single-channel solution for driving white LEDs at up to 600mA. It is suitable where linear regulation efficiency is acceptable compared to switching alternatives. Consider the thermal dissipation requirements associated with linear drivers when designing the PCB layout. Verify compatibility with the system's PWM signal frequency for optimal dimming performance.

LED Driver IC Part Context

This component belongs to the MIC4801 family of LED drivers designed by Microchip Technology. It is specifically engineered as a linear regulator rather than a switching converter. The device integrates protection features typical of modern LED driver ICs. It serves as a dedicated solution for portable devices needing reliable white LED illumination.

LED Driver IC Replacement Considerations

Check for MIC4801YM-TR if reel packaging is required instead of tubes. Verify functional equivalence with other Microchip single-channel WLED drivers if pinout compatibility is critical.
