STMicroelectronics Motor Control Solutions

Low voltage – 1.8V up to 75V

STMicroelectronics STSPIN drivers for 3-phase brushless DC (BLDC) motors include power drivers in a 3-phase bridge configuration and integrated solutions with built-in decoding logic for Hall-effect sensors. They also feature a PWM current controller to autonomously drive a BLDC motor through motion commands coming from the motor or motion control system host – a microcontroller, DSP, or FPGA. In addition to the integration of the power MOSFET and the associated driving circuitry, they include protection and diagnostic features for over-temperature, over-current, and under-voltage conditions, resulting in robust and reliable designs. Available in a wide selection of space-saving, thermally-enhanced packages, STSPIN 3-phase BLDC motor driver ICs provide a ready-to-use and optimized solution for motor and motion control systems in a wide range of voltage and current ratings and they are part of STMicroelectronics 10 and 15 years longevity program.
