MC3002 Series
1 cell lithium–ion/lithium–polymer battery protection IC
Outline
MC3002 series are protection IC with integrated MOS-FET for
protection of the rechargeable Lithium–ion or Lithium–polymer
battery.The overcharge, overdischarge and discharging and
charging overcurrent protection of the rechargeable one-cell
Lithium–ion or Lithium–polymer battery can be detected.

The resistors that are inserted into each pin are to protect the IC. They help to remove ESD and latch-up damages.
The capacitors help to reduce the effects of transient variations in voltage and electromagnetic waves, and to improve ESD
tolerance of the IC.
Please use either C2 or C3, or both of them by request of your application.
These values in the above figure are for example. Please choose appropriate values.
