UB261 Datasheet 1-cell Lithium-ion/polymer Battery Protection Ic

Manufacturer: Unisonic Technologies

Overview: UNISONIC TECHNOLOGIES CO., LTD UB261 Preliminary CMOS IC 1-CELL LITHIUM-ION/POLYMER BATTERY PROTECTION.

General Description

6 5 4 The UTC UB261 is a series of lithium-ion/lithium-polymer rechargeable battery protection ICs incorporating high accuracy voltage detection circuits and delay circuits.

The UTC UB261 is suitable for protection of single cell lithium-ion / lithium polymer battery packs from overcharge, over discharge and over current.

The ultra-small package and less required external ponents make it ideal to integrate the UTC UB261 into the limited space of battery pack.

Key Features
