Welcome to your new project. Imagine what you can build here.

Testing power output

Working from a single Li-Ion cell or dual AA batteries the TMC6300 is optimally suited for battery operated equipment. Operate a BLDC motor with block or sine-commutation using 6-line control from a CPU. Integrated powerMOSFETs handle motor current up to 2A. Protection and diagnostic features support robust and reliable operation. Its integrated charge-pump for best-in-class RDSon and ultra-low standby current ensure best efficiency even at low supply voltage and longest battery life.
