Lithium battery protection chip dw01+

Introduction The lithium battery protection chip dw01+M1 is a MOS for the voltage control pin, and M2 is a MOS for the current control pin. Only if the condition is met will the charging voltage and current be within the appropriate range, OD

Lithium battery protection chip dw01+

M1 is the MOS for the voltage driver pin, and M2 is the MOS for the current driver pin.

Only when the conditions are met, i.e. the load voltage and current are within the appropriate range, and OD and OC cause both tubes M1 and M2 to open At the same time, the battery charging and discharging circuit will be opened. R2 is used to detect current and convert it to voltage detection.

The 8205A is a dual-tube MOS tube. You can check the datasheet for specific parameters. This tube is characterized by extremely low internal resistance to avoid losses in the charge and discharge circuit. M1 and M2 are the two tubes of 8205 respectively.

What is lithium iron phosphate battery protection IC chip?

There are many board manufacturers lithium battery protection, but there are not many balance chipsibration that can be used.

The most commonly used are the two series of balancing chips HY2213 and HY2212.

Screen printing BB3A or CB3A, and AB3A, etc.

Stable performance. More and more people are using it.

It is used to protect the charging and discharging of lithium iron phosphate batteries. Few people currently use lithium iron phosphate, so few people make this integrated circuit. Taiwan Hongkang Technology manufactures this type of protection integrated circuit. , like Hy2112-HB, Hy2122-AB1A, etc. have an agent in mainland China, which should be called Saifan Technology.
