The controller of an electric bicycle is the core part that controls the motor, and it often has functions such as a motor lock system and high-speed control in electric bicycles. Meanwhile, the low-voltage MOS tube directly affects the circuit stability.
Therefore, how should the selection of a low-voltage MOS tube be made for the controller of an electric bicycle to be suitable for the circuit diagram of the electric bicycle?
Feihong Semiconductor, a manufacturer of low-voltage MOS tubes, received a consultation from Dou Sheng in Huai Bei city.
According to the description, Dou Designer hoped to find a domestic low-voltage MOS tube manufacturer to supply FHP120N9F4A model low-voltage MOS tubes for use in the drive circuit, aiming to replace Infineon MOS tubes.
Thus, he consulted Feihong Semiconductor hoping they could provide a sales solution for a domestic low-voltage MOS tube suitable for the drive circuit.
After understanding the situation, Feihong Semiconductor's team immediately adjusted their efforts to meet Dou Sheng's requirements.
Customize a domestically produced low-voltage MOS tube that matches and is suitable for the drive circuit, with parameters such as packaging, driving current, and gate resistance capable of replacing Infineon MOS tubes.
Based on the actual situation of Dou Sheng in Huai Bei city, it is recommended to use the FHP120N9F4A model low-voltage MOS tube in the drive circuit.

The FHP120N9F4A model product features low internal resistance, extremely low input capacitance, and low loss, making it very suitable for use in drive circuits. Importantly, the FHP120N9F4A model MOS tube ensures stable and orderly control in the drive circuit.
Finally, Huai Bei City Feihong Semiconductor successfully met Dou Sheng's demand for low-voltage MOS tube supply.
After testing the sample, Dou Sheng explained his decision to choose Feihong Semiconductor:
Dou Sheng decided on Feihong Semiconductor after analyzing and evaluating, because the FHP120N9F4A model is specifically designed for drive circuits.
Feihong Semiconductor provides direct sales services for domestic low-voltage MOS tubes, solving the need for low-voltage MOS tubes in electric bicycle controllers. Moreover, the price of domestic low-voltage MOS tubes is reasonable.
Dou Sheng mentioned that Feihong Semiconductor’s service attitude was sincere, enthusiastic, and thoughtful, making him feel satisfied when entrusting them with the sales customization of the FHP120N9F4A model low-voltage MOS tube.
The domestically produced FHP120N9F4A model can be specifically used for drive circuits. Feihong Semiconductor’s low-voltage MOS tube manufacturer strives to provide robust component supply guarantees for electronic manufacturers such as electric bicycles, MOSFET power switch circuits, smart speakers, and synchronous rectifier circuits.
