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
Chapter 7.8: Maximum charging time on page 20
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
Output voltage selection pin.
V
Output voltage sense pin.
It senses the battery voltage to control the voltage regulation loop.
