Brief Description:
1. Battery chip, also known as battery decoding IC, is often used in battery protection board. IC, which mainly communicates between mobile phone and battery
2. It plays the function of transmitting data, generally containing information such as battery power, battery voltage, charging current, charging times and battery manufacturers.
Function:
1. The charging limit voltage of BM41, 40 and other batteries of Mi phone battery is 4.35V, while the charging limit voltage of ordinary mobile phone battery is 4.2V.
2. The existence of chip ensures that the mobile phone can only use the battery containing the corresponding chip information when charging with charger, in order to avoid the short circuit caused by charging ordinary battery under high voltage and current.
