WARNING!
ESD SENSITIVE DEVICE
CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the ADP3820 features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.

EN
Enable. Pulling this pin to a logic Hi
or tying it to the input voltage will
enable the output. Pulling this pin
low will shutdown the controller.
Device Ground.
Output Voltage Sense. This pin is
connected to the MOSFET’s drain
and directly to the battery. Bypass to
ground with a 10
μ
F or larger
capacitor.
Gate Drive for the external MOS-
FET.
Input Voltage. This is also the positive
terminal connection of the current
limit resistor.
Current Sense. It is connected to the
more negative terminal of the current
limit resistor as well as the Power
MOSFET's source pin. IS pin must
be tied to the V
IN
pin if the current
limit resistor is not used.
