Note 1:
The input voltage range is specified with the external PFET off. When charging, the PFET turns on and the input voltage
(the output voltage of the constant-current power source) drops to very near the battery voltage. When the PFET is on, V
IN
may be as low as 2.5V.
Note 2:
BATT Input Current is the supply current to the device. When V
IN
is removed, the MAX1679 shuts down and the input current
is less than 1μA, even if there is an external R
ADJ
resistor (ADJ to GND).
