Motor drivers
ST, a pioneer in the field of motor and motion control, offers a wide range ofmotor drivers covering the requirements ofbrushed DC motors,stepper motors andbrushless DC motors over an extensive range of voltage and current ratings.
State-of-the-art motor drivers
Our line-up ofSTSPIN motor drivers embeds all the functions needed to drive motors efficiently and with thehighest accuracy, and include an advanced motion profile generator to relieve the host microcontroller, while ensuring robustness and reliability thanks to a comprehensive set of protection and diagnostic features.
Operating from a supply voltage as low as 1.8 V, the portfolio has been extended with the introduction oflow-voltage STSPIN motor drivers which enable power savings in battery-powered smart devices thanks to the best-in-class standby current of less than 80 nA.
The benefit of our10 and 15 year longevity program is available for our industrial grade STSPIN motor drivers.
