AOZ9004B

Single-Cell Battery Protection IC

with Integrated MOSFET

General Description

Features

The AOZ9004B is a battery protection IC with integrated dual

common-drain N-channel MOSFET. The device includes accu-

rate voltage detectors and delay circuits, and is suitable for pro-

tecting single-cell lithium-ion / lithium-polymer rechargeable

battery packs from overcharge, over-discharge, and over-

current conditions.

● Integrated common-drain N-channel MOSFET

● High-accuracy voltage detection circuit

◗ Overcharge detection accuracy ±25mV (+25°C), ±30mV

(-5°C to +55°C)

◗ Overcharge release accuracy ±50mV

◗ Over-discharge detection accuracy ±50mV

◗ Over-discharge release accuracy ±100mV

◗ Discharge over-current detection accuracy ±15mV

The AOZ9004B is available in an 8-pin TSSOP package and is

rated over a -40°C to +85°C ambient temperature range.

◗ Load short-circuit detection accuracy ±300mV

(AOZ9004BI), ±200mV (AOZ9004BI-01, 02, 03, and 04)

● ±20% accurate internal detection delay times

(external capacitors are unnecessary)

● Charger connection pin withstands up to 28V

● Wide operating temperature range -40°C to +85°C

● Low current consumption

◗ 3.0µA (Typ.), 5.5µA (Max.) in operation mode at

+25°C

● Small 8-pin TSSOP package

Applications

● Lithium-ion rechargeable battery packs

● Lithium-polymer rechargeable battery packs
