  • The STSPIN820 is a stepper motor driver which integrates, in a small QFN 4 x 4 mm package, both control logic and a low RDSon power stage.

    The integrated controller implements a PWM current control with fixed OFF time and a microstepping resolution up to 1/256th of the step.
    The device can be forced into a low consumption state.
    The device offers a complete set of protection features including overcurrent, overtemperature and short-circuit protection.

    Key Features

    • Operating voltage from 7 to 45 V
    • Maximum output current 1.5 Arms
    • RDSon HS + LS = 1 Ω typ.
    • Microstepping up to 1/256th of step
    • Current control with programmable OFF time
    • Current sensing based on external shunt resistor
    • Full protection set
    • Non-dissipative overcurrent protection
    • Short-circuit protection
    • Undervoltage lockout
    • Thermal shutdown
    • Standby low consumption
