Battery Management 0V Reference
(V DD )
A supply voltage of [V REG (Typical) + 0.3V] to 6.0V is
recommended for MCP73123, while a supply voltage
of [V REG (Typical) + 0.3V] to 12.0V is recommended for
MCP73223. Bypass to V SS with a minimum of 1 μF.
The V DD pin is rated 18V absolute maximum to prevent
sudden rise of input voltage from spikes or low cost
AC-DC wall adapter.
(V SS )
Connect to the negative terminal of the battery and
input supply.
3.6 Current Regulation Set (PROG)
The fast charge current is set by placing a resistor from
PROG to V SS during constant current (CC) mode.
3.2
Battery Charge Control Output
PROG pin also serves as charge control enable.
When a typical 200 k ? impedance is applied to PROG
(V BAT )
Connect to the positive terminal of the battery. Bypass
to V SS with a minimum of 1 μF to ensure loop stability
pin, the MCP73123/223 is disabled until the high
when the battery is disconnected. The MCP73123 is
designed to provide 3.6V battery regulation voltage for

Exposed Pad (EP)
LiFePO 4 batteries. Undercharge may occur if a typical
Li-Ion or Li-Poly battery is used.
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

simplify the assembly process. Connecting EP to V SS
3.4
Status Output (STAT)
is recommended.
STAT is an open-drain logic output for connection to an
LED for charge status indication in stand-alone
applications. Alternatively, a pull-up resistor can be
applied for interfacing to a host microcontroller. Refer to
charge cycle.
