Input pin of the power stage.
Supply voltage pin of the signal circuitry.
The operating input voltage ranges from 2.5 V to 12 V, and the
start-up threshold is 4 V.
Open-collector status pins.
Maximum charging time program pin.
It must be connected with a capacitor to GND to fix the maximum
charging time, see
page
Ground pin.
Shutdown pin.
When connected to GND enables the device; when floating
disables the device.
Temperature monitor pin.
It must be connected to a resistor divider including an NTC or PTC
resistor. The charge process is disabled if the battery temperature
(sensed through the NTC or PTC) is out of the programmable
temperature window see
21.
