A4988SETTR-T
by ALLEGRO(美国埃戈罗)
Microstepping control is the central function of Allegro's A4988SETTR-T, a driver IC for bipolar stepper motors. It is used in motion-control electronics where a controller needs to command motor movement through a step-and-direction interface. This record uses a surface-mount WQFN package with an exposed pad. The downloadable KiCad assets provide a 29-pin symbol and the WQFN-28_L5.0-W5.0-P0.50-BL-EP3.2 footprint, whose 29 pads include the exposed-pad position. A 3D model accompanies the electrical and layout files. The conversion has been used in real designs by 3 ProtoFlow engineers. Bring the part directly into ProtoFlow by opening the supplied library entry.
