AOZ1300 Programmable 4A Power Distribution Switch 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. ● maximum on-resistance ● Docking stations ● Notebook PCs ● RAID systems ● Telecom and Server hot-plug ● USB Power Distribution ● Compact PCI adapter Cards C1 1uF R1 100kΩ AOZ1300 FAULT OFF ON SLEW C3 10nF ISET R2 70kΩ VOUT TO USB PORT C2 4.7uF Figure High Current USB Host Page 1 of 12 AOZ1300 Ordering Information Part Number AOZ1300AI AOZ1300AIL Temperature Range -40°C to +85°C -40°C to +85°C Package SO-8 SO-8 Environmental RoHS Compliant Green Product All AOS products are offered in packages with Pb-free plating and compliant to RoHS standards.
