STMicroelectronics STDRIVE101 Demonstration Board (EVALSTDRIVE101)

STMicroelectronics STDRIVE101 Demonstration Board (EVALSTDRIVE101) provides an evaluation platform for the STDRIVE101 Triple Half-Bridge Gate Driver and the STL110N10F7 STripFET™ F7 Power MOSFET. The EVALSTDRIVE101 is designed to drive three-phase brushless DC motors, and it can be interfaced with different STM32 microcontrollers through the motor control connector. The board can be configured in single-shunt and three-shunt and can support FOC and six-step algorithms in both configurations. The Hall sensors connector and the phase sensing network present onboard allow users to implement both sensor and sensorless algorithms for motion control.  

The STMicroelectronics EVALSTDRIVE101 allows a full evaluation of the STDRIVE101 and its features, including the embedded comparator for overcurrent protection and the drain-source voltage sensing of each power MOSFET.

Features
