Pin description
1I
VIN
Input pin of the power stage.
2I
VINSNS
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
ST2-ST1 Open-collector status pins.
5I
TPRG
Maximum charging time program pin.
It must be connected with a capacitor to GND to fix the maximum
6
-
GND
Ground pin.
7I
SD
Shutdown pin.
When connected to GND enables the device; when floating
disables the device.
8I
TH
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
