STSPIN220 Datasheet Low voltage stepper motor driver Product status link STSPIN220 Product summary Order code STSPIN220 Package VFQFPN 3x3x1.0 16L Packing Tape & reel 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 Applications 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 • Reflex cameras 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.
