5.2.3
Driving the PROG2 input to a logic Low selects the low
USB port source current setting (maximum 100 mA).
Driving the PROG2 input to a logic High selects the
high USB port source current setting (Maximum
500 mA).
5.2.4
The power-good (PG) option is a pseudo open-drain
output. The PG output can sink current, but not source
current. However, there is a diode path back to the
input, and as such, the output should only be pulled up
to the input. The PG output is low whenever the input
to the MCP73871 device is above the UVLO threshold
and greater than the battery voltage. The PG output
can be used as an indication to the system that an input
source other than the battery is supplying power.

The timer enable (TE) input option is used to enable or
disable the internal timer. A low signal on this pin
enables the internal timer and a high signal disables
the internal timer. The TE input can be used to disable
the timer when the charger is supplying current to
charge the battery and power the system load. The TE
input is compatible with 1.8V logic.
