MCP73837/8
3.8
The MCP73837/8 USB-Port current regulation set
input (PROG2) is a digital input selection. A logic Low
selects a 1 unit load charge current; a logic High selects
a 5 unit loads charge current.
PROG2 also functions as the set point of precondition
and termination when USB-Port is present. When
PROG2 is floating, the MCP73837/8 enters in stand-by
mode.
3.9
Power Good (PG) is available only on MCP73837. PG
is an open-drain logic output for connection to a LED
for input power supply indication. Alternatively, a pull-
up resistor can be applied for interfacing to a host
microcontroller.

Timer Enable (TE) is available only on MCP73838.
(TE) enables the built-in safety timer when pull low and
disables the built-in safety timer when pull high.
