Overview
The HV857LMG-G is a single-channel, low-noise high-voltage electroluminescent (EL) lamp driver manufactured by Microchip Technology. It operates within a supply voltage range of 1.8V to 5V and supports an operating frequency of 1kHz. The device is housed in an 8-MSOP surface-mount package and functions across a temperature range of -40°C to +85°C. It features two outputs with a DC supply current of 25mA, designed for efficient EL lamp driving applications.
Feature Summary
- Single-channel architecture optimized for low-noise high-voltage EL lamp driving
- Wide input supply voltage compatibility ranging from 1.8V to 5V
- Surface-mount MSOP-8 packaging for compact board integration
Applications
- Electroluminescent backlighting systems
- Industrial control panel illumination
- Automotive instrument cluster displays
Procurement Notes
Verify the specific suffix 'MG' against official Microchip documentation to confirm pinout and thermal characteristics. Ensure the selected component matches the required 1.8V to 5V supply range and 1kHz operation frequency. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement specifications.
Selection Notes
Select this component when a single-channel solution for EL lamps is required with low noise performance. It is suitable for designs needing a wide supply voltage range including 1.8V logic levels. Consider the MSOP-8 package size for space-constrained applications requiring SMD mounting.
Part Context
This part belongs to Microchip's HV857 series of EL lamp drivers. It shares functional similarities with variants like HV857MG-G but differs in package type and specific electrical parameters. The series is designed for general-purpose EL lamp illumination in various electronic display and lighting applications.
Replacement Considerations
Check for direct substitutes such as HV857MG-G or HV857LK7-G. Verify that alternative packages (MSOP vs DFN) and voltage ranges are compatible with the existing design constraints before substitution.
