① High precision protection of excessive charging protection When the lithium ion battery is excessively charged, in order to prevent the internal voltage of the temperature rising, the charging state must be cut off. Protecting the IC will detect the battery voltage. When the excessive charging is detected, it will be detected. The power MOSFET of the over -charging detection is cut off and the charging is cut off. At this time, it should be paid attention to the high precision of the over -charging voltage. When the battery is charged, the charging of the battery to the full state is a problem that the user is very concerned. At the same time, taking into account the safety issue, it is necessary to cut off the charging status when the allowable voltage is met. To meet these two conditions at the same time, there must be a high -precision detector. The accuracy of the current detector is 25mV. This accuracy will need to be further improved.
② Reduce the power consumption of protecting IC As the use time increases, the voltage of the lithium -ion battery that has been charged will gradually decrease, and finally low to the specifications below the standard value. At this time, it is necessary to recharge again. As a result, the battery cannot continue to use due to excessive discharge. In order to prevent excessive discharge, protecting the IC must detect the battery voltage. Once below the excessive discharge detection voltage, the power MOSFET of the discharge side must be turned off and the discharge is cut off. But at this time the battery itself itself There are still natural discharge and protection of IC consumption current, so the current that protects IC consumption needs to be minimized.
③ The requirements of low -detection voltage and high -precision requirements for over -current/short -circuit protection must stop discharge immediately when short circuit. The detection of over -current is based on the RDS (ON) of the power MOSFET If the voltage at this time is higher than the current detection voltage is high, the discharge is stopped. In order to make the RDS (ON) of the power MOSFET effectively applied when the charging current and discharge current are effective, the impedance value needs to be as low as possible. At present, the impedance is about approximately about about the impedance. 20mq ~ 30mq, so that the current detection voltage can be lower.
④ When connecting high -voltage battery packs to the charger, there will be high -voltage generation when connecting, so the protection IC should meet the requirements of high voltage resistance.
