HV5522PG-G

Shift Registers Overview

The HV5522PG-G is a 32-channel serial-to-parallel converter with open drain outputs, manufactured by Microchip Technology. It operates within a logic supply voltage range of 10.8 V to 13.2 V and supports high-voltage output up to 220 V. The device features an 8 MHz shift register speed and CMOS-compatible inputs. It includes polarity select and blanking control logic, housed in a 44-lead PQFP package.

Shift Registers Feature Summary

• Provides 32 high-voltage current sinking channels with open drain outputs for driving loads requiring multiple-output capabilities.
• Integrates a 32-bit shift register and latch system allowing data shifting on clock transitions and storage via latch enable signals.
• Supports forward and reverse shifting options along with polarity inversion and global blanking functions for precise output control.

Shift Registers Applications

• AC-electroluminescent displays
• Inkjet print heads
• Electrostatic print heads

Shift Registers Procurement Notes

Verify the specific package variant (PQFP or PLCC) required for your design, as the PG suffix denotes the 44-lead PQFP form factor. Confirm lead-free compliance status through official datasheets or manufacturer documentation before finalizing procurement specifications.

Shift Registers Selection Notes

Select this component when designing circuits that require serial-to-parallel conversion for high-voltage loads such as AC electroluminescent panels. Ensure the application logic supply voltage falls within the 10.8 V to 13.2 V range and that the interface timing meets the specified clock frequency requirements.

Shift Registers Part Context

This device belongs to the HV5522 family of high-voltage interface components produced by Microchip Technology. It serves as a driver for applications needing multiple high-voltage current sinking capabilities, bridging low-voltage logic control with high-voltage load requirements.

Shift Registers Replacement Considerations

Consult official Microchip documentation for verified substitute part numbers. Cross-referencing should be performed based on pin compatibility, electrical characteristics, and package dimensions to ensure functional equivalence.

Shift Registers FAQ

How does the HV5522 handle data shifting direction?

The device supports both forward and reverse shifting options, allowing flexibility in how data is processed through the internal shift register.

What is the function of the BL input pin?

The BL (Blanking) pin sets all HVOUT pins to either low or high states depending on the current state of the POL (Polarity) input.
