1 / 12 page  Rev. 1. 3 August 2008 www.aosmd.com Page 1 of 12 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.
