STMicroelectronics STSPIN220, Stepper Motor Driver IC 16-Pin, QFN

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 protectionOperating 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
