HV859MG-G

Overview

The HV859MG-G is a high-voltage driver IC manufactured by Microchip Technology, designed for driving electroluminescent (EL) lamps with an area up to 5.0 square inches. It operates within an input supply voltage range of 1.8 V to 5.0 V and utilizes a single inductor with minimal passive components. The device is housed in an 8-pin MSOP package and supports surface-mount installation. It functions as a DC-to-DC converter suitable for display driver applications.

Feature Summary

• Designed specifically for driving electroluminescent lamps
• Utilizes a single inductor architecture for efficient power conversion
• Supports split supply configurations with enable/disable control

Applications

• Driving electroluminescent displays
• Backlighting systems for LCD panels
• Industrial control panel illumination

Procurement Notes

Verify the specific suffix MG-G confirms the 8-pin MSOP package and tape-and-reel orientation. Confirm RoHS compliance status through official documentation. Ensure the supplier provides valid traceability data for this specialized power IC. Cross-reference the manufacturer part number against current datasheets to avoid obsolete variants.

Selection Notes

Select this component when driving EL lamps up to 5.0 square inches is required. It is suitable for designs needing a compact solution using a single inductor. Consider the 1.8 V to 5.0 V input range compatibility with system power rails. Evaluate the MSOP-8 package constraints for PCB layout space.

Part Context

This part belongs to the HV859 family of high-voltage drivers from Microchip Technology. It is categorized under Display Drivers & Controllers. The MG-G suffix denotes the specific MSOP-8 packaging variant. Related parts include the HV859K7-G in a DFN package.

Replacement Considerations

The HV859K7-G serves as a pin-compatible alternative in an 8-pin DFN EP package. Verify thermal performance differences between MSOP and DFN packages before substitution.
