STSPIN220 Datasheet PDF - ST Microelectronics

The STSPIN220 is a stepper motor driver which integrates, in a small QFN 3 x 3 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.

●Key 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
