NEW Low-voltage monolithic motor drivers
ST has extended its portfolio of STSPIN motor drivers with the introduction of three new monolithic devices that simplify design, save space and are optimized for battery-powered stepper ( STSPIN220, with a position resolution of 256 microsteps per full step), DC brushed ( STSPIN240) and 3-phase brushless motors ( STSPIN230) in portable applications.
They operate from a supply voltage as low as 1.8 V, over a wide current and temperature range, and can be forced in a zero consumption state (with quiescent current less than 80 nA), which allows significant power savings for extended runtime of battery-powered IoT devices. Available in a 3 x 3 mm QFN package, they benefit from comprehensive built-in protection features including over-current, over-temperature and short-circuit for high ruggedness and reliability even in harsh industrial environments.
