Active production — BOM-fit note
The UC3717Q: Rated as a 1 A stepper motor controller, the part drives the winding current for bipolar stepper motors in half-step and full-step modes — the 1 A ceiling sets the torque-speed envelope for the connected motor.
RoHS compliance flag — legacy solder process
This part is RoHS non-compliant, meaning it contains lead or other restricted substances above the exemption thresholds. It is suited for BOMs with a RoHS exemption (e.g., leaded solder in high-reliability or military applications) or for designs that do not require RoHS conformance. This is typical for through-hole or large-pin-count surface-mount parts that are hand-placed or used in low-volume production.
