Part details & applications

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).
