TheAOZ9250DIisabatteryprotectionICwithintegrateddualcommon-drainN-channelMOSFET
The AOZ9250DI 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 AOZ9250DI is available in a 2mm x 4mm 6-pin DFN
package and is rated over a -40°C to +85°C ambient
temperature range
