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 drivers 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.
32-bit MCU-based BLDC motor drivers in tiny 7x7 mm QFN
The STSPIN32F0, STSPIN32F0A and STSPIN32F0B combine a 32-bit ARM® Cortex®-M0 core STM32F0 microcontroller and a three-phase, half-bridge gate driver in a tiny 7x7 mm QFN package, delivering the flexibility and power of a microcontroller-based drive with the convenience, simplicity and space-efficiency of a single IC.
The new STSPIN32F0B can operate from a supply voltage as low as 6.7 V, which is equivalent to two LiPo cells, making it ideal for battery-powered applications.
The STSPIN32F0A embeds three integrated operational amplifiers, while STSPIN32F0B offers one OpAmp but more additional general-purpose I/O ports (GPIO).
