Pin I/O Name Pin description
1IV
IN
Input pin of the power stage.
2IV
INSNS
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.
3 - 4 O ST
2
-ST
1
Open-collector status pins.
5IT
PRG
Maximum charging time program pin.
It must be connected with a capacitor to GND to fix the maximum
charging time, see Chapter 7.7: Maximum charging time on
page 21.
6 - GND Ground pin.
7ISD
Shutdown pin.
When connected to GND enables the device; when floating
disables the device.
8ITH
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 Chapter 8.1: NTC thermistor on page 23.
