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.
