Features• Input bus voltage from 6 V to 75 V with dedicated monitoring• Output current up to 20 Arms – Power stage based on the STL110N10F7 power

MOSFETs• STDRIVE101 embedded features:

– Two input strategies (enable / input with adjustable deadtime generation ordirect driving with interlocking)

– VDS sensing of the power MOSFETs– Overcurrent protection with internal comparator

• Three-shunt or single-shunt configurable current sensing• BEMF or Digital Hall sensor circuitries• NTC sensor for PCB temperature monitoring• Motor control connector compatible with a wide range of STM32 boards and

systems

Application• Power tools• e-Bikes• Fans and home appliances

DescriptionThe EVALSTDRIVE101 is a demonstration board based on the STDRIVE101, athree-phase gate driver, and the STL110N10F7 power MOSFETs.

The EVALSTDRIVE101 is designed to drive three-phase brushless DC motors and itcan be interfaced with different STM32 microcontrollers through the motor controlconnector.

The board can be configured in single shunt and three-shunt and can support FOCand six-step algorithms in both configurations.

The Hall sensors connector and the phase sensing network present on-board allowto 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-sourcevoltage sensing of each power MOSFET.

2 Waste and recycling

TheEvaluation Board is not to be disposed of as urban waste. At the end of its life cycle, differentiatedwaste collection must be followed. Consult local authorities for more information on the proper disposalchannels and recycling centers. It is mandatory to collect separately the Demonstration Board and make sure it isdelivered to the appropriate waste management and recycling centers. As of 15 August 2018, in all countriesbelonging to the European Union, the Demonstration Board is subject to the requirements of WEEE Directive2012/19/EU, and therefore it is forbidden to dispose of the Demonstration Board as undifferentiated waste or withother domestic waste. Incorrect disposal of the Demonstration Board may cause damage to the environment andmay incur fines based on specific countries’ rules, regulations, and laws.
