HV513K7-G

Shift Registers Overview

The HV513K7-G is an 8-channel serial-to-parallel converter featuring high-voltage push-pull outputs, manufactured by Microchip Technology. It operates with a logic supply voltage (VDD) ranging from 4.5 V to 5.5 V and supports a high-voltage supply (VPP) up to 250 V. The device includes a shift register speed of 8 MHz at VDD = 5 V. It offers polarity selection, blanking, High-Z control, and short-circuit detection capabilities. Available in a 32-lead WQFN package, it functions within a junction temperature range of -40°C to +85°C.

Shift Registers Feature Summary

• Provides eight high-voltage push-pull outputs capable of driving small capacitive loads such as piezoelectric transducers.
• Integrates output short-circuit detection that flags faults when outputs fail to reach the required state.
• Includes break-before-make circuitry to reduce crossover current during output state transitions.
• Features internal pull-up resistors on POL, BL, LE, and Hi-Z inputs for simplified interface design.

Shift Registers Procurement Notes

Verify the specific ordering suffix K7 corresponds to the 32-lead WQFN package configuration. Confirm lead-free status via RoHS compliance documentation. Ensure availability aligns with current manufacturing cycles. Validate pinout compatibility with existing PCB layouts before finalizing procurement decisions.

Shift Registers Selection Notes

Select this component for applications requiring multiple medium-current high-voltage outputs controlled via serial interfaces. Consider the 8 MHz clock speed and latched data outputs for precise timing requirements. Evaluate thermal dissipation needs based on the 32-lead QFN package characteristics and operating conditions.

Shift Registers Part Context

The HV513 series serves as a low-voltage-to-high-voltage level shifter designed for driving capacitive loads. It combines an 8-bit shift register with latches and control logic for polarity and blanking. The device facilitates cascading through a dedicated data output buffer, enabling multi-device configurations for expanded channel counts.

Shift Registers FAQ

How does the short-circuit detection function operate?

The SHORT pin asserts a logic low if an output fails to track its required state. For VPP greater than 150V, it flags shorts where HVOUT exceeds 10V when expected low or falls below VPP-100V when expected high.

What is the purpose of the Hi-Z input?

The Hi-Z input sets all high-voltage outputs into a high-impedance state when driven low, effectively disconnecting the outputs from the load.
