GENERAL DEscriptION

The SGM42601 is a motor driver device with two integrated H-bridges that can run a bipolar stepper motor. The device can operate over a wide input voltage range of 2.5V to 12V, and each H-bridge of the SGM42601 can deliver up to 600mA RMS (or DC) continuously (at VCC = 5V, TJ = +25℃).

Internal over-current and over-temperature circuits prevent the device from being in over-stress condition, while a fault output simplifies stalling sensing, which is a useful feature for most applications. Aiming for battery-powered applications, it can go into low-power mode for increased battery life.

The device is available in a Green TQFN-4×4-16L package.
