HV518PJ-G

Display Drivers Overview

The HV518PJ-G is a display driver and controller manufactured by Microchip Technology, designed for Vacuum Fluorescent Display (VFD) applications. It features 32 channels with an 80V output capability, housed in a 44-pin PLCC package. The device operates on a single 5V supply voltage and supports serial input interfaces. It functions within a temperature range of -40°C to +85°C and is RoHS compliant.

Display Drivers Feature Summary

• Provides 32-channel serial-to-parallel conversion for VFD control
• Supports high-voltage outputs up to 80V for direct display driving
• Operates on a standard 5V logic supply voltage

Display Drivers Applications

• Vacuum Fluorescent Display (VFD) panel drivers
• Industrial control panel interfaces
• Consumer appliance user interfaces

Display Drivers Procurement Notes

Verify the specific suffix 'PJ-G' to confirm the 44-pin PLCC package variant, as other suffixes may indicate different packages or lead-free status. Ensure compatibility with existing PCB footprints requiring PLCC-44 components. Confirm RoHS compliance requirements for your assembly process. Check for moisture sensitivity level (MSL) handling instructions during storage and reflow soldering procedures.

Display Drivers Selection Notes

Select this component when a 32-channel VFD driver with serial interface is required. The 80V output rating suits standard VFD filament and grid voltages. Consider the PLCC-44 package if surface-mount assembly is preferred over DIP options like the HV518P-G. Verify that the system logic levels match the 5V operating voltage of the device.

Display Drivers Part Context

This part belongs to Microchip's HV518 series of display drivers. It is functionally similar to the HV518P-G but differs in packaging, utilizing a 44-pin PLCC instead of a 40-pin PDIP. Both variants serve the same core purpose of driving VFDs via serial data inputs, offering flexibility in board layout and assembly methods.

Display Drivers Replacement Considerations

The HV518P-G is a pin-compatible alternative only if the package difference (PLCC vs. PDIP) is accommodated by the design. No direct electrical substitute is confirmed in public documentation without verifying package-specific pinouts.
