Procurement Notes
Verify the obsolete status and end-of-life designation before finalizing designs. Confirm package dimensions and pinout compatibility with existing PCB footprints. Ensure supply chain availability for replacement components due to discontinuation risks associated with this specific part number.
Selection Notes
Select this component for low-voltage piezo applications requiring minimal external circuitry. The integrated design reduces board space and simplifies layout. Consider the limited current output when sizing actuators. Verify thermal performance within the specified ambient temperature range during system integration.
Part Context
This part belongs to onsemi’s motor drivers and controllers family, specifically targeting piezo actuator solutions. It complements other motion control ICs by providing dedicated drive capabilities for precision positioning tasks in consumer electronics and optical devices.
Replacement Considerations
Public confirmed substitute part numbers are not available for this discontinued component. Designers should evaluate alternative piezo drivers from the manufacturer or industry suppliers that match the voltage, current, and package requirements.
