Procurement Notes
Verify the specific suffix 'G' indicates RoHS compliance status through official Microchip documentation before procurement. Confirm the moisture sensitivity level requirements for your assembly process. Ensure the SOIC-8 package dimensions match your PCB footprint design constraints. Check current production lifecycle status to avoid obsolescence risks during long-term manufacturing.
Selection Notes
Select this component when a dedicated driver for a single EL lamp is required in mobile devices. Consider the 5 V input compatibility with standard battery supplies. Evaluate the 140 V output capability against the specific lamp impedance requirements. Compare the SOIC-8 package size against available board space constraints relative to other driver options.
Part Context
This part belongs to the HV823 family of general lamp drivers intended for portable electronic devices. It serves as a specialized display driver within Microchip's broader portfolio of controller and driver integrated circuits. The series is engineered to provide efficient power management for electroluminescent displays in compact form factors.
Replacement Considerations
