OPERATIOU
the timing resistor connected to R
T
, keeps switch S1
closed to sample the thermistor:

RT
= 309k
The external RC network is driven to approximately 4.5V
and settles to a final value across the thermistor of:

This voltage is stored by C7. Then the switch is opened for
a short period of time to read the voltage across the
thermistor.

RT

When the t
HOLD
interval ends the result of the thermistor
testing is stored in the D flip-flop (DFF). If the voltage at
NTC is within the limits provided by the resistor divider
feeding the comparators, then the NOR gate output will be
low and the DFF will set T
BAD
to zero and charging will
continue. If the voltage at NTC is outside of the resistor
divider limits, then the DFF will set T
BAD
to one, the charger
will be shut down, FAULT pin is set low and the timer will
be suspended until T
BAD
returns to zero (see Figure 4).
