uP8208P/Q
Li-Ion/Polymer 2/3/4-Cell
Second Protection IC + Voltage Regulator
Features
General Description
The uP8208P/Q series is used for secondary protection of High Accuracy Voltage Detection Circuit for
lithium-ion rechargeable batteries, and incorporates a high-
accuracy voltage detection circuit and a delay circuit. Short
circuits between cells accommodate series connection of
two to four cells. In order to drive an external RTC.Avoltage
regulator of 3.3V(uP8208P) or 3.0V(uP8208Q) is
incorporated in uP8208P/Q. uP8208P/Q is available in the
WDFN2x2-8L package.
