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.

Each Cell

Overcharge Detection Voltage n (n = 1 to 4)

4.3V to 4.6V (in 50mV steps)

Accuracy: 20mV (+25^oC)

Accuracy: 25mV (0^oC to +60^oC)
