Electric traction for small vehicles is getting more and more popular among two- and three-wheelers ranging from pedal-assist e-bikes to e-scooters and motorbikes.

ST offers an AEC-qualified integrated chipset for the ECU (Electronic Control Unit) up to 48V electric BLDC traction motors.

    • Combining the SPC56P-Discovery board and EVAL-L9907 (up to 20A) or EVAL-L9907H (up to 120A) evaluation board with related Graphical User Interface (GUI) STSW-L9907 or STSW-L9907-H, you can easily evaluate your brushless motor control applications.
