STSPIN220

STSPIN220 is a low voltage 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. Battery-powered stepper motor applications such as pop-up camera control for smartphones, point of sale (POS) devices, portable printers, PC peripherals and accessories, robotics, toys and reflex cameras.

• Operating voltage range from 1.8 to 10V
