The fast charge current is set by placing a resistor from
PROG to V
PROG pin is rated up to 5V with 6V absolute maximum
value.
PROG pin also serves as charge control enable.
When a typical 200 kΩ impedance is applied to PROG
pin, the MCP73113/4 device is disabled until the high

The Exposed Thermal Pad (EP) shall be connected to
the exposed copper area on the Printed Circuit Board
(PCB) for the thermal enhancement. Additional vias on
the copper area under the MCP73113/4 device can
improve the performance of heat dissipation and
simplify the assembly process.
