only if the backup capacitor on VDD is large enough to
maintain power for greater than the 10ms blanking time.
The detection that the adapter is unplugged and
plugged in again is implemented by monitoring the VIN
signal. The adapter is unplugged when VIN drops below
VIN = ~0.75V, and it is plugged in when VIN becomes
greater than VIN = ~0.75V. To ensure the monitoring of
this lower threshold, an external storage capacitor at the
VDD pin is necessary. When the input voltage VIN drops
below 4V, power for some internal VIN monitoring circuit-
ry is supplied by the external capacitor at the VDD pin.
This capacitor is supplied by VIN through a diode and is
internally limited to 5.5V.
Adapter Not Present (VIN < VUVLO)
When the input voltage VIN drops below 4.4V, P1 is
turned off automatically and P1 does not turn on again
until the adapter is unplugged (VIN < ~0.75V) and
plugged in again. When the adapter is not present, P1 is
kept off with the gate-source resistor (which is internal for
the MAX4960 and external for the MAX4959), and the
CB pin controls the battery switchover pFET P2.
