HV861K7-G

Overview

The HV861K7-G is a low-noise, dimmable dual EL lamp driver manufactured by Microchip Technology. It operates within a supply voltage range of 2.5 V to 4.5 V and dissipates up to 1.6 W of power. The device is housed in a QFN-16 surface-mount package and supports installation via SMD/SMT techniques. It functions reliably across an ambient temperature range from -40°C to +85°C. The component is classified under Display Drivers & Controllers and Driver ICs subcategories.

Feature Summary

• Provides dual channel driving capability specifically designed for Electroluminescent (EL) lamps.
• Integrates dimming functionality to allow adjustable light output control.
• Engineered with low noise characteristics to ensure clean signal performance.

Applications

• Backlighting systems for industrial displays
• Control panel illumination in automotive interfaces
• Instrument cluster lighting in appliance domains

Procurement Notes

Verify the End-of-Life (EOL) status before procurement planning, as the component is listed as discontinued. Confirm RoHS compliance details through official manufacturer documentation. Ensure compatibility with existing PCB footprints for the QFN-16 package. Check humidity sensitivity handling requirements during storage and assembly processes.

Selection Notes

Select this component when designing circuits requiring dedicated dual-channel EL lamp driving with integrated dimming capabilities. Consider the QFN-16 package constraints for thermal management and board space. Evaluate the 2.5 V to 4.5 V operating voltage range against system power rails. Assess the -40°C to +85°C temperature range against environmental operating conditions.

Part Context

This part belongs to Microchip's Display Drivers & Controllers portfolio, specifically within the Driver ICs subcategory. It is distinct from other HV series drivers like the HV845K7-G, which utilizes a QFN-12 package. The HV861K7-G is categorized separately from battery management ICs such as the MCP73861T-I/ML.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the End-of-Life status, alternative sourcing or design modifications may be necessary.
