MCHPHV5622PG-G
Overview
The HV5622PG-G is a 32-channel serial-to-parallel converter designed for high-voltage applications requiring open-drain outputs. It operates with a logic supply of 10.8V to 13.2V and features a 32-bit shift register capable of clock speeds up to 8 MHz. Each of the 32 outputs is rated for a maximum voltage of 230V and a minimum sink current of 100mA.
Why Choose This Part
The device offers high-density control with 32 channels in a single 44-PQFP package, significantly reducing PCB footprint for high-voltage arrays. Its open-drain outputs can handle up to 230V, and the inclusion of a diode to Vpp allows for efficient power recovery in capacitive loading scenarios. The forward and reverse shifting options provide flexible routing and layout possibilities on complex boards.
Applications
Key Specifications
Getting Started
When designing with the HV5622PG-G, ensure the logic supply (VDD) remains within the 10.8V to 13.2V range and provide adequate decoupling for the high-voltage rail. Standard CMOS logic levels are compatible with the clock, data, and strobe inputs, making it easy to interface with 12V-logic MCUs or level-shifted 3.3V/5V controllers. Proper PCB creepage and clearance must be maintained between the high-voltage output pins to prevent arcing.
