HV518P-G

Display Drivers Overview

The HV518P-G is a display driver and controller manufactured by Microchip Technology, designed specifically for Vacuum Fluorescent Display (VFD) applications. It features 32 serial input channels capable of driving high-voltage loads up to 80V. The device operates on a single 5V power supply and supports through-hole mounting in a PDIP-40 package. It functions within an industrial temperature range from -40°C to +85°C and includes humidity sensitivity classification.

Display Drivers Feature Summary

• Provides serial-to-parallel conversion for VFD segment and grid control
• Supports high-voltage output stages rated for 80V loads
• Operates with standard 5V logic interfaces

Display Drivers Applications

• Vacuum Fluorescent Display (VFD) panel drivers
• Industrial instrument front panels
• Consumer appliance control interfaces

Display Drivers Procurement Notes

Verify the specific suffix 'G' indicates RoHS compliance status as per the manufacturer's current documentation. Confirm the PDIP-40 package availability and lead times directly with authorized distributors or Microchip sales representatives. Ensure design-in compatibility with existing PCB footprints and thermal management requirements for the specified operating temperature range.

Display Drivers Selection Notes

Select this component when designing systems requiring direct drive of VFD segments and grids via a serial interface. It is suitable for applications needing high-voltage outputs without external transistor arrays. Consider the PDIP-40 package constraints if surface-mount alternatives like PLCC are not required. Verify voltage headroom requirements against the 80V maximum rating.

Display Drivers Part Context

This part belongs to Microchip's HV series of display drivers, which integrate high-voltage outputs for direct VFD control. The HV518 variant specifically offers 32 channels, distinguishing it from lower-channel count models in the family. It serves as a dedicated solution for replacing discrete driver circuits in legacy and modern VFD designs.

Display Drivers Replacement Considerations

Check for pin-compatible alternatives such as the HV518PJ-G for PLCC packaging options. Verify functional equivalence with other Microchip HV series drivers if channel counts or package types differ.
