Analog Devices / Maxim Integrated TMC2300 Low Voltage Stepper Motor Drivers
Analog Devices TMC2300 Low Voltage Stepper Motor Drivers are ideal for battery-operated, space-, and standby-power critical driver applications. The drivers feature StealthChop™ silent drive technology that enables non-bugging motion control for portable, home, and office applications. The devices have a highly efficient power stage, boosted by an internal charge pump for best-in-class RDSon resistance. This provides high motor current from a tiny package even at low supply voltages. Dual AA batteries can be drained to 2.0V typically (voltage must not drop below 1.8V, provide sufficient supply buffer capacitors).
