MM3284

MITSUMI Protection for Lithium-Ion Batteries (for double protection) MM3284 Series Protection for Lithium-Ion Batteries (for double protection) Monolithic IC MM3284 Series Outline This IC is a double protection IC for lithium battery of 1-cell to 4-cell. It detects the battery voltage for every cell. It includes a timer, eliminating an external capacitor for overcharge detection delay that is used for our conventional ICs, which allows programmable detection delay time. www.DataSheet4U.com Features 1. Overcharge detection voltage 4.0~4.5V Accuracy ±30mV (-40~85°C) 2. Current consumption (VCELL=3.5V) 2.5µA typ. 3. Current consumption (VCELL=2.5V) 2.0µA typ. 4. Maximum rating 28V 5. Operating voltage range: 2~24V 6. No external capacitance required for delay time (Delay time is determined by the internal circuit, ranging from 1s to 12s upon request) Packages SOT-26A SSON-6A Applications 1. Laptop PCs 2.
