AOZ1300

Programmable 4A Power Distribution Switch

General Description

Features

The AOZ1300 is a current-limited power distribution

switch intended for applications that require circuit

protection. The device operates from a 2.7V to 6.0V

input supply and provides up to 4A load current.

AOZ1300 offers robust fault protection features including

over-current/short-circuit protection and thermal overload

protection. The current limit is programmable with an

external resistor. An open-drain fault indicator is provided

to alert a system controller of thermal overload, over-

current, and short-circuit events. A 24ms fault blanking

time eliminates false alarms.

● 40mΩ maximum on-resistance

● 4A maximum continuous current

● 2.7V to 6.0V operating voltage

● Resistor programmable current limit

● Reverse current blocking

● Thermal overload protection

● Very fast short-circuit response time

● Fault latch with 24ms blanking time

● Open-drain fault indicator

● 1µA shutdown current

The AOZ1300 employs internal soft-start circuitry to

control inrush current due to highly capacitive loads

associated with hot-plug events. An adjustable slew rate

control pin provides additional slew rate control if needed.

Applications

● Docking stations

● Notebook PCs

The AOZ1300 is available in SO-8 package.

● RAID systems

● Telecom and Server hot-plug

● USB Power Distribution

● Compact PCI adapter Cards
