STMicroelectronics Motor Control Solutions are a portfolio of products for low voltage motor control applications. These products include monolithic driver ICs, power MOSFETs, IGBTs, gate drivers, power modules, and dedicated microcontrollers to address a broad range of applications. STMicroelectronics has boards and reference designs for Low Voltage Motors. This includes < 100V all the way to High Voltage Motors 600V up to 1200V. Permanent Magnet synchronous motor and Brushless DC motors are replacing DC brush motors in more applications for advantages like higher efficiency, quieter operation, and better reliability. Despite their different structures, all three-phase permanent magnet motors (BLDC, PMSM) are driven by a pulse-width-modulated (PWM) three-phase bridge (three half-bridges) to supply the motor with variable frequency and amplitude of voltages and currents.
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.
