E-Bike

Electric bicycles (E-Bikes) have an integrated electric motor and rechargeable battery, making it an eco-friendly, zero-emission vehicle. They need lightweight systems to reduce weight for handling comfort and improved electrical efficiency. Power components play a key role in this. By increasing the efficiency of the electronics, an E-Bike can travel further for the same weight of battery or the same distance with a smaller battery pack. Slim and space optimized designs with high power density are essential to support state-of-the-art concepts.

Design considerations

  • Require a high battery capacity and an efficient motor often housed in space constraint positions
  • Typically use a Brushless DC motor built into the wheel hub and often rated under 750 W
  • LFPAK56 power MOSFETs have best-in-class power density and current rating, and low heat and high efficiency.
  • LED and Gate drivers provide low cost custom solutions driven by component reduction demand
  • ESD protection for interfaces to avoid field failure

 

Automotive relay replacement - Reliability meets space savings

A relay is often perceived as the ideal device with perfect input/output isolation. Unfortunately, this is not the case. MOSFETs are rapidly becoming the option of choice offer reliability and space savings.
