GD32F107RCT6_SSG4920N Introduction

Today I will introduce to you a domestic FET that is suitable for lithium battery protection boards and can replace MOS tubes such as AO3401: NCE3401.

In response to this demand, Xinjie can produce N-channel trench process MOS transistors with small internal resistance and good overcurrent resistance - NCE80H12, the on-resistance of NCE80H12 is less than 6mΩ, the output current can reach 120A, and the motor torque is better , .

However, in terms of structure, there is a big difference between them. In order to better understand the mechanism of power MOSFET, we must first recall the mechanism of low-power FET. . Working principle of power MOS tube Power MOS tube is developed from low-power MOS tube. The following describes the principle of the MOS transistor with the structure of an N-channel enhancement type low-power MOSFET.

The functions of the MOS tube in the protection board are: 1. Detect overcharge, 2. Detect over-discharge, 3. Detect over-current during charging, 4. Detect over-current during discharge, 5. Detect over-current during short circuit.

The lithium battery is mainly composed of two blocks, the battery cell and the lithium battery protection board PCM.
