ST’s STSPIN drivers for 3-phase brushless DC (BLDC) motors includes power drivers in a 3-phase bridge configuration and integrated solutions with built-in decoding logic for Hall-effect sensors.
Our BLDC motor controllers 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.
Turnkey motor control modules that provide all the functions required such as speed, position and current loop execution and real-time connectivity to the master, are also available. With their compactness, these modules are ideal for direct installation on a permanent magnet synchronous motor (PMSM).
The STSPIN portfolio comes with extensive evaluation hardware and software as well as a technical documentation toolbox to help minimize time to market.
The benefit of our 10 and 15 years longevity program is available for our industrial grade STSPIN motor drivers.
