MCHPHV5622PJ-G
Overview
The HV5622PJ-G is a 32-channel serial-to-parallel converter designed for high-voltage applications requiring open-drain outputs up to 220V. It features a high-speed shift register capable of 8MHz clock frequencies and includes CMOS-compatible inputs for easy interfacing with standard microcontrollers. The device is particularly effective for driving capacitive or resistive loads in systems that require a large number of high-voltage switches.
Why Choose This Part
This device offers a high density of 32 channels in a single PLCC-44 package, significantly reducing PCB real estate for high-channel-count systems. Its open-drain outputs support up to 220V, and the inclusion of a diode to Vpp allows for efficient power recovery when switching capacitive loads.
Applications
Getting Started
To interface with the HV5622PJ-G, connect your microcontroller to the CLOCK, DATA IN, and STROBE pins using standard 12V CMOS logic levels. Ensure the VDD supply is maintained between 10.8V and 13.2V for reliable operation. When prototyping, use a PLCC-44 socket to avoid heat stress on the package during manual soldering of the 1.27mm pitch pins.
