CHG
Charge Indicator Output
CHG
is an open-drain current source for indicating
charge status. Table 1 describes the state of
CHG
dur-
ing different stages of operation.
CHG
is a nominal 12mA current source suitable for dri-
ving a charge-indication LED. If the MAX1508 is used
in conjunction with a microprocessor, a pullup resistor
to the logic I/O voltage allows
CHG
to indicate charge
status to the μP instead of driving an LED.
Soft-Start
An analog soft-start algorithm activates when entering
fast-charge mode. When the prequalification state is
complete (V
BATT
exceeds +2.5V), the charging current
ramps up in 3ms to the full charging current. This
reduces the inrush current on the input supply. Since
the MAX1508Y and MAX1508Z do not have a prequali-
fication state, they automatically enter soft-start upon
activation.
