PIN DESCRIPTIONS
DESCRIPTION
No connect.
Ground pin.
No connect.
4.2V, 2 mA reference output pin.
Pin to set the maximum charging current in the Fast charge (CC) mode. Also, reflects actual
charging current. A resistor between this pin and ground sets the charge current, I_CH:
R_{I S E T}
=
1_----0_---0_---0_{- ---}×_{-- ---}2_---._-5_----V--
I_CC
Enable pin. Logic high (default value) enables charging. Logic low disables charging.
No connect.
No connect.
Charging status indicator pin (open-drain output).
Thermistor input pin from battery monitoring circuit.
Charger output pin.
Battery voltage remote sense pin.
4.2V output pin, connect a cap to ground to increase stability.
No connect.
No connect.
Positive input supply voltage pin, which powers the charger.
