Acceptable ABV/BBV Range:
Before initial timer: 0.16V~2 V
After initial timer:1.2V~2V
Temperature Protection Mode:
If temperature is too high, battery charging
is regarded as completed. If temperature is
too low, function of
disabled, just as thermistor is not existing.

Battery Voltage Measurement
The AIC1782 measures the battery voltage
through ABV and BBV pins, which is connected
to battery positive terminal through a resistor-
divider network, as shown in Fig. 2. The ac-
ceptable limit of divided battery voltage is de-
termined by the input voltage of SEL3 pin.

Battery Temperature Measurement
The AIC1782 employs a negative temperature
coefficient (NTC) thermistor to measure the
battery
’
s
temperature. The thermistor is inher-
ently nonlinear with respect to temperature. To
reduce the effect of nonlinearity, a resistor-
divider network in parallel with the thermistor is
recommended. A typical application circuit is
shown in Fig. 3.
