Product overview

Description

The STSPIN220 is a stepper motor driver which integrates, in a small VFQFPN 3 x 3 x 1.0 mm package, both control logic and a low RDS (on) power stage.

The integrated controller implements PWM current control with fixed OFF time and a microstepping resolution up to 1/256th of a step.

The device is designed to operate in battery-powered scenarios and can be forced into a zero-consumption state, allowing a significant increase in battery life.

The device offers a complete set of protection features including overcurrent, overtemperature and short-circuit protection.

  • All features

    • Operating voltage: from 1.8 to 10 V
    • Maximum output current: 1.3 Arms
    • RDS(ON) HS + LS = 0.4 Ω typ.
    • Microstepping up to 1/256th of a step
    • Current control with programmable off-time
    • Full protection set
      • Non-dissipative overcurrent protection
      • Short-circuit protection
      • Thermal shutdown
    • Energy saving and long battery life with standby consumption less than 80 nA
