AOZ1300
Programmable 4A Power Distribution Switch
General Description
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.
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.
The AOZ1300 is available in SO-8 package.
