This reference design features a low voltage motor driver STSPIN220, which is designed for driving stepper motors. The STSPIN220 is a bipolar stepper motor driver. It combines control logic and a low drain to source resistance H-bridge power stage in a small QFN 3×3 package. The device can operate from a power supply ranging from 1.8 up to 10V. It can output a maximum current of 1.3A RMS. The STSPIN220 consumes 1.3mA when the power stage is OFF and 1.95mA when the power stage is enabled. When the device is on standby mode, it consumes a maximum current of 80nA. Read More
