LT3572EUF#TRPBF

Full Half-Bridge (H Bridge) Drivers Overview

The LT3572EUF#TRPBF is a highly integrated dual piezo motor driver manufactured by Analog Devices Inc. It operates from an input voltage range of 2.7V to 10V and utilizes an internal boost converter to drive two piezo motors at up to 40V. The device features a 900mA boost converter and includes soft-start capabilities with separate enable controls for each piezo driver and the boost converter. It is housed in a 20-QFN (4x4) package.

Full Half-Bridge (H Bridge) Drivers Feature Summary

• Dual full-bridge architecture for independent control of two piezo motors
• Integrated 900mA boost converter enabling high-voltage operation from low input supplies
• Separate enable pins allow individual control of each piezo driver and the boost stage

Full Half-Bridge (H Bridge) Drivers Applications

• Piezoelectric motor actuation systems
• Precision positioning devices requiring dual-axis control
• Medical instrumentation utilizing piezo actuators

Full Half-Bridge (H Bridge) Drivers Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging when sourcing components. Confirm the manufacturer is Analog Devices Inc. or its predecessor Linear Technology, as part numbers may vary slightly across legacy documentation. Ensure the order matches the exact 20-QFN package specification required for your PCB layout.

Full Half-Bridge (H Bridge) Drivers Selection Notes

Select this component when designing systems that require driving multiple piezo elements from a single low-voltage source without external inductors. The integrated boost simplifies design compared to discrete solutions. Consider the 2.7V to 10V input range compatibility with standard battery or rail supplies. Evaluate thermal performance within the 20-QFN package for your specific power dissipation requirements.

Full Half-Bridge (H Bridge) Drivers Part Context

This part belongs to the LT3572 family of piezo drivers. It is designed to simplify the interface between microcontrollers and piezoelectric actuators. The integration of the boost converter and dual bridges reduces board space and component count. It serves as a specialized solution for motion control applications where precise voltage regulation and fast switching are necessary.

Full Half-Bridge (H Bridge) Drivers Replacement Considerations

Check for LT3572EUF#PBF if leaded packaging is preferred over the surface-mount QFN variant. Verify functional equivalence with other dual piezo drivers if supply constraints exist, ensuring voltage ratings and current capabilities match the original design specifications.
