HV5522PJ-G

Shift Registers Overview

The HV5522PJ-G is a low-voltage to high-voltage serial-to-parallel converter featuring open drain outputs. It integrates a 32-bit shift register, 32 latches, and control logic for polarity selection and blanking. The device operates with a logic supply voltage of 10.8 V to 13.2 V and supports high-voltage output up to 220 V. Data shifts on the clock falling edge at frequencies up to 8 MHz. It is housed in a 44-lead PLCC package.

Shift Registers Feature Summary

• Provides 32-channel high-voltage current sinking capabilities with open drain outputs.
• Includes dedicated inputs for polarity inversion and output blanking control.
• Supports forward and reverse shifting options within the internal shift register.
• Features diode to VPP connection to allow efficient power recovery.

Shift Registers Applications

• Inkjet and electrostatic print heads
• AC-electroluminescent displays
• Plasma panels
• Vacuum fluorescent displays

Shift Registers Procurement Notes

Verify the specific ordering suffix PJ indicates the 44-lead PLCC package configuration. Confirm RoHS compliance status via the G suffix designation. Ensure the application circuit matches the recommended operating conditions for VDD and HVOUT voltages. Check datasheet revision history for any updates to electrical characteristics or pin descriptions before finalizing procurement specifications.

Shift Registers Selection Notes

Select this component when multiple-output high-voltage current sinking is required. It is suitable for driving loads such as plasma panels or large matrix LCD displays. Verify that the logic supply voltage range aligns with the system's 10.8 V to 13.2 V requirement. Consider the 44-lead PLCC package constraints for PCB layout and thermal dissipation needs.

Shift Registers Part Context

This part belongs to the HV5522 family of serial-to-parallel converters manufactured by Microchip Technology. It serves as a driver for applications requiring high-voltage interface capabilities. The device is designed to interface with standard CMOS-compatible logic inputs while managing high-voltage output stages.

Shift Registers FAQ

How does the Latch Enable (LE) input affect data transfer?

Data transfers from the shift register to the latches when the LE input is high. The data remains stored in the latch when LE is low.

What is the function of the Polarity (POL) input?

The POL input inverts the polarity of the HVOUT pins, allowing control over the output state relative to the blanking signal.
