HV53001T-E/KWX

Specialized ICS Overview

The HV53001T-E/KWX is a high-voltage driver integrated circuit manufactured by Microchip Technology, housed in a 105-ball 9x9 mm TFBGA package. It features 16 push-pull output channels capable of ±135V swing with a minimum source/sink current of 24 mA. The device integrates an SPI interface supporting up to 32 MHz clock speeds and a DC/DC boost converter powered by a single 2.7V to 5.5V input rail. Key functional blocks include a high-voltage driver, control logic, and current sensing outputs mapped to low-voltage analog signals.

Specialized ICS Feature Summary

• 16-Channel Push-Pull Output: Capable of driving up to ±135V with Return-To-Zero (RTZ) and High-Impedance states.
• Integrated Boost Converter: Includes a power MOSFET and flyback controller to generate internal high-voltage rails from a 2.7V–5.5V supply.
• Current Sensing: Global current sensor function monitors charge/discharge currents via VPPSENSE and VNNSENSE pins with a 3.1 V/V scale factor.
• Safety Protections: Features overvoltage protection, short-circuit detection, and overtemperature monitoring with fault signal outputs.

Specialized ICS Applications

• Surface Haptic Actuators
• MEMS Drivers
• Piezo Drivers

Specialized ICS Procurement Notes

Verify the ordering suffix 'T' indicates Tape & Reel packaging as specified in local product fields. Confirm the 'E' suffix denotes the extended temperature range (-40°C to +125°C). Ensure compatibility with 3.3V logic levels for the SPI interface. Check for moisture sensitivity level (MSL) requirements during storage and handling.

Specialized ICS Selection Notes

Select this component when a high-voltage driver with integrated power generation is required to minimize external BOM. The 105-TFBGA package requires careful PCB layout for thermal management and high-voltage clearance. Ensure the host MCU supports SPI communication at up to 32 MHz. Verify that the application load capacitance does not exceed 250 pF per channel.

Specialized ICS Part Context

The HV53001 belongs to Microchip's high-voltage driver family designed for compact integration. It combines the driver stage, control logic, and power conversion into a single solution. This integration reduces board space compared to discrete designs using separate drivers and boost controllers.

Specialized ICS Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Evaluate pin-compatible alternatives only if they support identical voltage ratings and SPI interfaces.
