3.3
No connect.
3.4
STAT is an open-drain logic output for connection to an
LED for charge status indication in standalone
applications. Alternatively, a pull-up resistor can be
applied for interfacing to a host microcontroller. Refer to

3.6
The fast charge current is set by placing a resistor from
PROG to V
PROG pin also serves as charge control enable. When
a typical 200 kΩ impedance is applied to PROG pin,
the MCP73213 is disabled until the high-impedance is
removed. Refer to Section 5.5 “Constant Current
Mode - Fast Charge” for details.
3.7
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 MCP73213 device can
improve the performance of heat dissipation and
simplify the assembly process.
