The MCP73833/4 continuously monitors the voltage at
the V
voltage drops below the recharge threshold, another
charge cycle begins and current is once again supplied
to the battery or load. The recharge threshold is factory
set. Refer to Section 1.0 “Electrical Characteristics”
for recharge threshold options.
4.8
The MCP73833/4 limits the charge current based on
the die temperature. The thermal regulation optimizes
the charge cycle time while maintaining device
reliability.

The MCP73833/4 suspends charge if the die
temperature exceeds +150°C. Charging will resume
when the die temperature has cooled by approximately
+10°C. The thermal shutdown is a secondary safety
feature in the event that there is a failure within the
thermal regulation circuitry.
