FAN8831MPX

Overview

The FAN8831MPX is a fully integrated piezoelectric motor driver manufactured by onsemi, designed for tactile feedback applications. It operates within a supply voltage range of 2.7V to 5.5V and supports load voltages from 30V to 60V. The device utilizes parallel interface control and features two half-bridge outputs built with power MOSFET technology. Housed in a 24-MLP (4x4) surface-mount package with a bare solder pad, it is rated for junction temperatures between -55°C and 150°C.

Feature Summary

• Fully integrated design combining control logic and power stage for piezoelectric actuators
• Dual half-bridge output configuration supporting high-voltage loads up to 60V
• Parallel interface for simplified digital control connections

Applications

• Tactile feedback systems
• Piezoelectric motor drivers

Procurement Notes

Verify component authenticity through authorized channels as the part status is End-of-Life. Confirm that the 24-MLP package dimensions and thermal requirements align with the target PCB layout. Ensure supply chain sources provide valid traceability documentation given the discontinuation date of October 1, 2021.

Selection Notes

Select this component specifically for piezoelectric actuator control requiring high voltage swing capabilities within a compact footprint. The integrated power MOSFETs eliminate the need for external switching elements. Consider the wide operating temperature range for harsh environment deployments where standard drivers may fail.
