Lithium-Ion Battery ICs INDEX	\| HTML \| PDF \|

[Outline]

MM3284 series are secondary protection IC using high voltage CMOS process for overcharge protection of the rechargeable lithium-ion or lithium-polymer secondary battery. The high accuracy overcharge detection of each cell of the rechargeable 1 to 4 serial cells lithium-ion or lithium-polymer secondary battery is possible. With a timer circuit built-in, it is possible to set overcharge detection delay time.

[Features] (Unless otherwise specifi ed, Topr=+25°C)
