MIC4827YMM-TR

Overview

The MIC4827YMM-TR is an EL lamp driver IC manufactured by Microchip Technology, designed for driving electroluminescent displays. It operates within a supply voltage range of 1.8 V to 5.5 V and supports output voltages up to 90 V. The device utilizes a boost topology and functions at frequencies between 60 Hz and 1 kHz. Packaged in an 8-MSOP surface-mount case, it features low quiescent current consumption of 21 µA. The component is rated for operation across a temperature range of -40°C to +85°C and complies with RoHS3 standards.

Feature Summary

• Integrated boost converter topology for efficient EL panel driving
• Low power consumption suitable for battery-operated applications
• Compact 8-MSOP surface-mount package design

Applications

• Electroluminescent (EL) display backlighting
• Industrial control panel indicators
• Instrumentation front panels

Procurement Notes

Verify the specific ordering suffix matches the required tape-and-reel configuration. Confirm that the 8-MSOP package dimensions align with PCB footprint requirements. Ensure input voltage levels remain within the specified 1.8 V to 5.5 V operational range during system integration.

Selection Notes

Select this component when driving single-output EL lamps requiring high voltage from low-voltage sources. Consider the 60 Hz to 1 kHz frequency range for optimal display performance. Evaluate the 8-MSOP package size against available board space constraints.

Part Context

This part belongs to the MIC4827 family of EL drivers. It shares functional similarities with the MIC4826 but may differ in specific electrical characteristics or pin configurations. Both are designed for similar low-power EL lighting applications within the same operating temperature ranges.

Replacement Considerations

The MIC4826YMM-TR is a documented substitute within the same product family. Verify compatibility regarding specific drive parameters before implementation.
