O
VREF
External reference voltage pin.(reference voltage is 1.8 V±2%)
13
I/O
IEND
Charge termination pin.
A resistor connected from this pin to GND fixes the charge termination current threshold
End-of-charge current on page 19). The voltage across the resistor is proportional to the
current delivered to the battery (Gas Gauge function).
14
I
VPRE
Multifunction pin.
A resistor connected to GND allows the user to adjust the pre-charge voltage threshold
VPRETH.
If the pin is floating, VPRETH = 2.8 V. If the voltage on VPRE pin is lower than 0.8 V, VPRETH =
2.8 V and the charge is not automatically terminated when I < IENDTH.
If the voltage on VPRE goes lower than 0.5 V (edge sensitive), the maximum charging time is
reset.
15
I
IPRG
Charge current program pin.
A resistor connected from this pin to GND, fixes the fast charge current value (ICHG), with an
accuracy of 7%.
16
I
IPRE
Pre-charge current program pin.
If the pin is floating IPRETH is equal to 10% of ICHG. If IPRETH has to be programmed at a
different value, the pin has to be connected to GND or VREF
, through a resistor see
Table 2.
