Description
The EVALSTDRIVE101 is a demonstration board based on the STDRIVE101, a three-phase gate driver, and the STL110N10F7 power MOSFETs. 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 on-board allow to implement both sensor and sensorless algorithms for motion control. The 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.
