Thermistor
The MP2610 has a built-in NTC resistance
window comparator, which allows MP2610 to
sense the battery temperature via the thermistor
packed internally in the battery pack to ensure a
safe operating environment of the battery.

(NTC)
A resistor with appropriate value should be
connected from VREF33 to NTC pin and the
thermistor is connected from NTC pin to GND.
The voltage on NTC pin is determined by the
resistor divider whose divide ratio depends on
the battery temperature. When the voltage of pin
NTC falls out of NTC window range, MP2610 will
stop the charging. The charger will restart if the
temperature goes back into NTC window range.
