Technical content
1 cell lithium–ion/lithium–polymer battery protection IC MC3002 Series 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. (1) Range and accuracy of detection/release voltage Accuracy±27mV (Topr=−5°C to +60°C) (2) Range of detection delay time Discharging overcurrent detection delay time ...Selection from 8ms, 12ms, 16ms, 20ms, 34ms (4) The overcharge detection delay timer reset time function (function for the pulse charge) is provided. fixed (5) Low current consumption (For “Charger connection release” the overdischarge release condition.) Max. 0.5µA (For “Voltage release” the overdischarge release condition.) (6) MOS-FET (7) Absolute maximum ratings *2 Please inquire to us about details of the setting of Overdischarge detection and release voltage. Outline Features (Unless otherwise specified, Ta=25°C)
Pin no. Symbol Function
1 S1 S1 is a source pin of Discharge MOS-FET and a negative power supply, which is connected
to the negative terminal of the battery.
2 VDD VCC is a positive power supply pin, which is connected to the positive terminal of the battery
through Rvcc (330 to 470 ohm). 3 V- V- is an input pin that detects overcurrent. This pin is connected to the source terminal of Charge MOS-FET through Ridt (2.7 KΩ).
4 S2 S2 is a source pin of Charge MOS-FET, which is connected to a negative power supply
terminal of chargers. - D D is a common pin of two drains of Charge MOS-FET and Discharge MOS-FET. D must be open electrically.

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.
