The descriptions of the pins are listed in
TABLE 3-1:
3.1
A supply voltage of [V
recommended. Bypass to V
3.2
Connect to the positive terminal of the battery. Bypass
to V
when the battery is disconnected.
3.3
Connect to the negative terminal of the battery and
input supply.
3.4
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
Table 5-1

The MCP73830/L is always enabled with an internal
pull-down resistor. Pulling the CE pin high will enter
Standby mode.
3.7
The Exposed Thermal Pad (EP) should be connected
to the exposed copper area on the Printed Circuit
Board (PCB) for thermal enhancement purposes.
Additional vias on the copper area under the
MCP73830/L device can improve the performance of
heat dissipation and simplify the assembly process.
