On any street, it is common to see electronic bikes (e-bikes) being used as a mode of transportation. Over the past 10 years, manufacturers have steadily produced more than 20 million e-bikes per year. Because of the high demand, there is a need for complete solutions with high reliability and innovative features, such as new battery management solutions for features like control or electronic locks.

This design uses a combination of advanced MCU, power and BMS devices to provide a complete solution for any kind of e-bike.

System Benefits:

  • Mature solution support with a motor control algorithm, supports both square and sinewave drivers
  • High-accuracy battery charge monitor that improves distance
