The Pentium II processor with on-die cache mobile module
MMC-2 operates with a maximum input voltage of 21 volts.
This circuit locks out the input voltage if it exceeds the
maximum 21 volts. The output of this circuit, Pin 14 of the
LM339 comparator, is an open-collector output. It is low
when the applied voltage at PWR is more than 21 volts. This
voltage can be calculated with the following equation:

Figure 8 shows that the circuit detects an overcurrent
condition and cuts off the input voltage applied to the
Pentium II processor with on-die cache mobile module
MMC-2. This circuit has two different current limit trip points,
which accounts for the
Overcurrent Protection: Circuit Description
Different maximum current drain by the Pentium II processor
with on-die cache mobile module MMC-2 at different input
voltages. Assuming the AC Adaptor is 18.0 volts and the
battery is a 3x3 Li-Ion configuration with a minimum voltage
of 7.5 volts, the maximum current for the above circuit can
be calculated using the following expression:
