When NTC1 pin detects that the voltage is 0.47v, it represents the battery temperature of 55 ℃; when NTC1

voltage is lower than 0.47v, it stops charging; when NTC1 voltage is higher than 0.7V, it restores the charging

current to normal value

In the state of discharge:

When NTC1 pin detects that the voltage is 2.13v, it represents low temperature of battery - 20 ℃; when

NTC1 voltage is higher than 2.13v, it stops discharging; when NTC1 voltage is lower than 2.04v, it resumes

discharging.

When NTC1 pin detects that the voltage is 0.47v, it represents the battery high temperature of 55 ℃; when

NTC1 voltage is lower than 0.47v, it stops discharging; when NTC1 voltage is higher than 0.55v, it resumes

discharging.

NTC2 pin is used to detect the temperature of wireless charging coil. When NTC2 pin detects that the voltage

is 0.3V, it means that the coil temperature exceeds 70 degrees, and the wireless charging TX will be turned off.

When NTC2 voltage is higher than 0.55v (coil temperature is lower than 50c), recover wireless charging TX.

*The above temperature range refers to NTC resistance zl104fbxv050 (B = 3950). Other models have

differences and need to be adjusted.

If NTC is not required in the application, 51K resistance shall be connected to the ground at NTC pin, and

floating or direct grounding is not allowed.

VCC

VCC is a normally open 3.1V LDO with a load capacity of 50mA.
