LT3572EUF#PBF

Full Half-Bridge (H Bridge) Drivers Overview

The LT3572EUF#PBF is a highly integrated dual piezoelectric motor driver manufactured by Analog Devices Inc. It operates from a supply voltage range of 2.7V to 10V and drives two piezo motors at up to 40V using an internal boost converter capable of 900mA. The device features separate enable controls for each piezo driver and the boost converter, along with slew rate control. It is housed in a 20-QFN (4x4) package and supports surface mount installation.

Full Half-Bridge (H Bridge) Drivers Feature Summary

• Dual full-bridge architecture for independent piezo motor control
• Integrated high-voltage boost converter for 40V operation from low input
• Individual enable pins for drivers and boost stage management
• Controlled slew rates to minimize electromagnetic interference

Full Half-Bridge (H Bridge) Drivers Applications

• Piezoelectric motor actuation systems
• Precision positioning stages requiring dual-axis control
• Optical focus mechanisms in imaging devices
• Micro-fluidic pump drivers

Full Half-Bridge (H Bridge) Drivers Procurement Notes

Verify the exact suffix #PBF indicates lead-free RoHS compliance when ordering. Confirm the 20-QFN (4x4) package dimensions match your PCB footprint design. Ensure the input power supply can deliver sufficient current for the 900mA boost requirement during peak load conditions to maintain stable 40V output.

Full Half-Bridge (H Bridge) Drivers Selection Notes

Select this component when driving two independent piezoelectric actuators from a single low-voltage source. It is suitable for applications requiring precise voltage control and soft-start capabilities. Consider thermal performance in the QFN package if operating near maximum temperature ratings or continuous duty cycles.

Full Half-Bridge (H Bridge) Drivers Part Context

This part belongs to the LT3572 family of piezo drivers. It differs from other PMICs like the LTC3577 by focusing specifically on high-voltage piezo actuation rather than general portable device power management. The EUF suffix denotes the specific 20-lead QFN package variant.

Full Half-Bridge (H Bridge) Drivers Replacement Considerations

Direct substitutes are not explicitly listed in public documentation. Evaluate other dual-channel piezo drivers from Analog Devices or competitors that support 40V output and similar QFN packaging. Verify pin compatibility and electrical specifications before substitution.
