AOZ9004D

Single-Cell Battery Protection IC

General Description

Features

The AOZ9004D is a battery protection IC with integrated

dual common-drain N-channel MOSFET. The device

includes accurate voltage detectors and delay circuits,

and is suitable for protecting 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

◗ Load short-circuit detection accuracy ±200mV

◗ Charge over-current detection accuracy ±30mV

The AOZ9004D is available in a 2mm x 5mm 4-pin DFN

package and is rated over a -40°C to +85°C ambient

temperature range.

● ±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 2mm x 5mm 4-pin DFN package

Applications

● Lithium-ion rechargeable battery packs

● Lithium-polymer rechargeable battery packs
