Low voltage silent stepper motor driver 2…11V, up to 1.2A with zero standby current 256 µSteps, CoolStep, StallGuard2 and Stealt

The TMC2300 low voltage stepper motor driver is intended for battery-operated, space and standby-power critical driver applications. Its silent drive technology StealthChop™ enables non-bugging motion control for portable, home and office applications. A highly efficient power stage, boosted by an internal charge pump for best in-class RDSon resistance, provides high motor current from a tiny package even at low supply voltages. With this, dual AA batteries can be drained down to typically 2.0V (voltage must not drop below 1.8V, provide sufficient supply buffer capacitors).
