While sourcing 40uA, When NTC voltage is lower than 0.718V, it changes to 80uA; When NTC

voltage is high than 1.7V, it changes to 20uA; While sourcing 20uA, When NTC voltage is lower than

0.678V, it changes to 40uA.

While using a typical NTC thermistor of 103AT, protection threshold and NTC voltage in discharge

mode is as below:

Resisters can be in series or parallel with the NTC thermistor to change the protection temperature

range. If not needing NTC protection, NTC pin should connect a 10KΩ resister to ground.
