The Texas Instruments UC3172AQP is a voice coil motor controller rated for 1A output current, designed to drive the actuator coil in hard-disk drive head-positioning or similar precision linear-motion stages. The part is listed under the Analog & Data Acquisition category, reflecting its role as a mixed-signal actuator driver rather than a standalone power stage.
Lifecycle and compliance
RoHS non-compliant — the part contains lead (Pb) above the exemption threshold and is not suitable for assemblies requiring full RoHS conformance without a waiver.
Package and sourcing
Supplied in Bulk packaging — loose units in an anti-static tube or tray, not tape-and-reel. This suits low-volume prototyping or repair-stock replenishment where reel quantities are unnecessary. No stock-holding claim is made.
