A supply voltage of [V
recommended. Bypass to V
4.7 µF.
3.2
Connect to positive terminal of battery. Drain terminal
of internal P-channel MOSFET pass transistor. Bypass
to V
when the battery is disconnected.
3.3
STAT is an output for connection to an LED for charge
status indication. Alternatively, a pull-up resistor can be
applied for interfacing to a host microcontroller.
STAT is a tri-state logic output on the MCP73831 and
an open-drain output on the MCP73832.

Preconditioning, fast charge and termination currents
are scaled by placing a resistor from PROG to V
The charge management controller can be disabled by
allowing the PROG input to float.
3.6
There is an internal electrical connection between the
Exposed Thermal Pad (EP) and the V
be connected to the same potential on the Printed
Circuit Board (PCB).
Vias are recommended to add from land area of EP to
a copper layer on the other side of the PCB for better
thermal performance.
