The SGM42622B is a low voltage stepper motor driver with control logic and low RDSON MOSFET power stages all integrated in a small TQFN package.
This device uses fixed off-time PWM current control for two independent H-bridges and is capable for fine microstepping resolution up to 1/256. Aimed for battery- powered applications, it can go to near zero-power standby mode for increased battery life.
A full set of protection features are provided including over-current, short-circuit, and thermal shutdown.
The SGM42622B is available in a Green TQFN-3×3-16L package. It operates over an ambient temperature range of -40℃ to +85℃.
