temperature is lower than 2 degrees Celsius (greater than 0.50V) or the temperature exceeds 43 degrees

Celsius (less than 0.39V), the charging stops. The charging current limit value of the BAT terminal between

2~17 degrees Celsius (0.27V) is 0.1C, and C is equal to the battery capacity set by FCAP.

In the discharge state, the discharge is normal between -20 and 60 degrees Celsius, but when the

temperature is lower than -20 degrees Celsius (greater than 1.39V) or higher than 60 degrees Celsius

(less than 0.24V), the discharge stops.

NTC sixth gear:

In the charging state, the charging is normal between 0 and 45 degrees Celsius, but when the

temperature is lower than -10 degrees Celsius (greater than 0.86V) or the temperature exceeds 55

degrees Celsius (less than 0.28 V), the charging stops. The charging current limit value of the BAT terminal

is 0.2C between -10~0 degrees Celsius (0.55V) or between 45~55 degrees Celsius (0.28V), and C is equal

to the battery capacity set by FCAP.

In the discharge state, the discharge is normal between -20 and 55 degrees Celsius, but when the

temperature is lower than -20 degrees Celsius (greater than 1.39V) or higher than 55 degrees Celsius

(less than 0.28V), the discharge stops.

*Note:

After detecting the abnormal temperature of the NTC, it resumes normal operation when the

temperature is ±5 degrees Celsius of the protection temperature. In the brackets after the above

temperature, the NTC pin voltage corresponding to the temperature is written. The calculation method is:

the current discharged by the NTC pin * the NTC resistance value at the temperature.

The NTC resistance parameter referenced in the above temperature range is 10K@25℃ B=3380.

Other models are different and need to be adjusted.

If the scheme does not require NTC, the NTC pin should be connected to the ground with a 10k

resistor, and cannot be left floating or grounded directly.
