MIC2842AYMT-TR

LED Driver IC Overview

The MIC2842AYMT-TR is a four-channel linear white LED driver designed for mobile device applications. It operates from an input voltage range of 3 V to 5.5 V and delivers output current up to 150 mA per channel. The device features digital control via a single-wire interface, enabling precise brightness adjustment and color mixing. It supports backlighting and camera flash functions with an operating temperature range of -40°C to +125°C.

LED Driver IC Feature Summary

• Four-channel linear architecture for driving white LEDs directly from battery sources
• Single-wire digital control interface for brightness and color management
• Integrated thermal protection and shutdown modes for system safety

LED Driver IC Applications

• Portable display backlighting in mobile devices
• Keypad backlighting systems
• Camera flash and torch applications

LED Driver IC Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging with a standard quantity of 5000 units. Confirm the package type is 10-pin UDFN (TMLF) with an exposed pad. Ensure the component meets RoHS compliance standards required for your assembly process. Check for any recent production change notices regarding pinout or electrical specifications before finalizing procurement.

LED Driver IC Selection Notes

Select this component when a low-profile solution for multi-channel WLED driving is required. It is suitable for designs needing digital dimming without complex PWM hardware. Consider the 150 mA per channel limit for LED string sizing. The linear topology simplifies design but requires attention to power dissipation and thermal management within the UDFN package constraints.

LED Driver IC Part Context

This part belongs to the MIC2842 series of linear LED drivers from Microchip Technology. It is functionally related to the MIC2843A and MIC2844, differing primarily in channel count and specific control features. The MIC2842AYMT-TR specifically offers four channels, whereas other variants may offer different configurations for similar mobile lighting applications.

LED Driver IC Replacement Considerations

Direct substitutes include other MIC2842 variants with compatible pinouts. Verify that alternative parts support the same 3 V to 5.5 V input range and single-wire digital interface. Ensure the replacement package matches the 10-TMLF footprint for board compatibility.
