AOZ9006DIL
Single-Cell Battery Protection IC
with Integrated MOSFET
General Description
The AOZ9006DIL 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.
The AOZ9006DIL is available in a 2mm x 5mm 6-pin
DFN package and is rated over a -40°C to +85°C
ambient temperature range.
