Product details

Voice coil motor controller rated 1 A

The UC3172ADWP is a voice coil motor controller delivering 1 A continuous output, designed for precision positioning in hard-disk drive actuators, optical pickups, and other closed-loop linear motion systems where a voice coil actuator provides the feedback path.

Active lifecycle, RoHS non-compliant

However, it is RoHS non-compliant, which means it contains lead or other restricted substances above the RoHS threshold. For BOMs that require RoHS conformance, an exemption or a lead-free alternate must be sourced.

Sourcing and supply posture

For buyers needing to fill a BOM line, this part can be specified into production with no last-time-buy risk given its active lifecycle status.

Frequently asked questions

Is UC3172ADWP RoHS compliant?

No, the UC3172ADWP is RoHS non-compliant. Verify your BOM's regulatory requirements before specifying.

What is the closest functional equivalent to UC3172ADWP?

A functional peer is the DRV8811PWPR, a stepper motor driver with 1.9 A output current and a wider temperature range (-40°C to 150°C). However, the DRV8811 is a bipolar stepper driver, not a dedicated voice coil controller, so the control interface and application differ. The UC3172ADWP is purpose-built for voice coil actuation.

Is UC3172ADWP suitable for voice coil motor driver applications?

Yes, the UC3172ADWP is specifically described as a voice coil motor controller rated for 1 A output, making it suitable for driving voice coil actuators in precision positioning systems.
