5.9
The MCP73830/L suspends charging if the die tem-
perature 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.
5.10
The charge status output of the MCP73830/L is open-
drain, and, as such, has two different states: Low (L),
and High-Impedance (Hi-Z). The charge status out-
puts can be used to illuminate the LEDs. Optionally,
the charge status output can be used as an interface
to a host microcontroller. The faulty indication of a pre-
conditioning timer also indicates defective batteries,
when it fails to pass preconditioning threshold during
the given time.
