BYS6621_MDS9753ERH 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.

MOS tubes like NCE80H12 convert the DC power in the battery into AC power when the electric vehicle is running normally, thereby driving the motor to run.

MOS tube 3306 product features 1. RDS(on)=7mΩ@VGS=10V 2. Lead-free green equipment 3. Low resistance switch to reduce conduction loss 4. High avalanche current.

There are three parasitic capacitance parameters in the MOS tube specification, namely: input capacitance Ciss, output capacitance Coss, and reverse transfer capacitance Crss. What do the three capacitance parameters represent in the body of the tube? How did it form? .

. The characteristics of a MOSFET can be characterized by a transfer characteristic curve and a drain output characteristic curve. Figure 3 shows the handling characteristics of a certain FET. The transfer characteristic refers to the relationship curve between the gate voltage UGS and the corresponding drain current ID when the voltage UDS between the drain and the source is at a certain fixed value.

For example, electronic fuel injection system, anti-lock brake control, anti-skid control, traction control, electronically controlled suspension, electronically controlled automatic transmission, electronic power steering, etc. The electronic device that can be used independently in the environment has no direct relationship with the performance of the car itself. .

In the lithium battery protection board, the most important thing is to protect the chip and MOS tube.
