STMicroelectronics Low-Voltage STSPIN Motor Drivers

STMicroelectronics STSPIN Motor Drivers are a selection of ICs used for applications in a wide range of power ratings, motor types, and varied system partitioning. STSPIN motor drivers can be used to embed all functions to drive motors efficiently with the highest accuracy. These functions include an advanced motion profile generator to relieve the host microcontroller, and a comprehensive set of protection and diagnostic features.

STSPIN ICs use an adaptive current decay control scheme and innovative voltage mode driving for enhanced torque control accuracy that results in motion smoothness. Built-in protection and diagnostic schemes help attain long-term reliability for harsh factory automation environments. The STSPIN line-up are available in a wide selection of packages that addresses a wide selection of motor and motion control system design requirements.
