4.7.4.3
The Celeron processor mobile module MMC-1 operates with
a maximum input voltage of 21 volts. This circuit locks out
the input voltage if it exceeds the maximum
4.7.4.4
Figure 8 shows that the circuit detects an overcurrent
condition and cuts off the input voltage applied to the
Celeron processor mobile module. This circuit has two
different current limit trip points. This takes into account the
different maximum current drain by the Celeron processor

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:
mobile module at different input voltages. Assuming the AC
Adaptor voltage is 18 volts and the battery is a 3x3 Li-Ion
configuration with a minimum of 7.5 volts, the maximum
current for the above circuit can be calculated using the
following expression:
