MIC4826BMMTR

Lighting, Ballast Controllers Overview

The MIC4826BMMTR is an EL lamp driver IC manufactured by Microchip Technology, housed in an 8-MSOP package. It operates on a boost topology with a single output. The device supports an input voltage range of 1.8 V to 5.5 V and delivers a minimum output voltage of 90 V. Operating frequencies span from 60 Hz to 1 kHz. It functions within a temperature range of -40 °C to +85 °C.

Lighting, Ballast Controllers Feature Summary

• Integrated EL lamp driver controller optimized for electroluminescent displays
• Boost topology design for efficient high-voltage generation from low supply voltages
• Wide operating frequency range supporting standard display refresh rates

Lighting, Ballast Controllers Applications

• Electroluminescent (EL) display backlighting systems
• Industrial control panel indicator lighting
• Automotive instrument cluster illumination

Lighting, Ballast Controllers Procurement Notes

Verify the specific suffix 'BMM' against official Microchip documentation to confirm exact tape-and-reel specifications and moisture sensitivity level. Ensure compatibility with existing PCB footprints for the 8-MSOP package. Cross-reference the datasheet revision date to validate current manufacturing status and any recent material changes.

Lighting, Ballast Controllers Selection Notes

Select this component when driving EL panels requiring a single-channel boost driver. Confirm that the required output voltage exceeds the 90 V minimum specification. Evaluate the 1.8 V to 5.5 V input range against available system power rails. Consider the 8-MSOP package constraints for thermal management and board space limitations in compact designs.

Lighting, Ballast Controllers Part Context

This part belongs to the MIC4826 family of EL drivers. It shares functional similarities with the MIC4827YMM-TR but may differ in specific electrical characteristics or packaging details. The MIC4826 series is designed specifically for low-power electroluminescent applications, distinguishing it from general-purpose LED drivers or DC/DC converters in the Microchip portfolio.
