Overview
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, overcurrent, 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.
