MCHPHV5522
Overview
The HV5522 is a 32-channel serial-to-parallel converter designed for high-voltage applications requiring open-drain outputs up to 220V. It features an 8 MHz shift register and provides a minimum sink current of 100 mA per channel, making it ideal for driving large arrays of high-voltage loads from a low-voltage logic source.
Why Choose This Part
The device integrates 32 channels into a single package, significantly reducing component count for high-density driver boards. It supports both forward and reverse shifting for layout flexibility and includes a dedicated diode to Vpp for efficient power recovery during inductive switching.
Applications
Getting Started
Designers should provide a VDD supply between 10.8V and 13.2V for the logic section and ensure CMOS-compatible levels for the clock and data inputs. Use the Polarity (POL) and Blanking (BL) pins to globally manage output states without shifting new data. Thermal management is critical when sinking the maximum 100 mA across multiple channels simultaneously.
