5.2.2
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 PG output should only be pulled
up to the input. The PG output is low whenever the
input to the MCP73833 is above the UVLO threshold
and greater than the battery voltage. If the supply

5.2.3
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.

The current regulation set input pin (PROG) can be
used to terminate a charge at any time during the
charge cycle, as well as to initiate a charge cycle or
initiate a recharge cycle.
Placing a programming resistor from the PROG input to
V
float or by applying a logic-high input signal, disables
the device and terminates a charge cycle. When
disabled, the device’s supply current is reduced to
100 µA, typically.
