Description

General part information

MAX15068 Series

The MAX15068 offers ORing function and hot-swap features for two input-supply-rail applications requiring the safe insertion and removal of circuit line cards from a live backplane. The device integrates dual ORing MOSFET controllers, a single hot-swap controller, electronic circuitbreaker protection, and power monitoring in a single package. The device operates on 2.9V to 18V supply voltages.The device regulates the forward voltage drop across the ORing MOSFETs to ensure smooth current transfer from one supply to the other without oscillation. The ORing MOSFET turns on quickly to reduce the load voltage drop during supply switchover. If the input supply fails or is shorted, a fast turn-off minimizes reverse-current transients.The device implements a foldback current limit during hotswap startup in order to control inrush current, thereby keeping the hot-swap MOSFET under safe operating area (SOA). After the hot-swap startup cycle is completed, onchip comparators provide active current-limit protection against short-circuit and overcurrent faults. The load is disconnected from the input quickly in the event of a fault condition.The device provides a current-sense amplifier output. A voltage proportional to the current delivered to the system can be read directly at the IPMON pin.The device is factory-calibrated to deliver accurate overcurrent protection with ±5% accuracy. During an overcurrent-fault condition, the device enters an autoretry mode. The device features an adjustable slew-rate control during startup. Additional features include power-good and fault-indicator outputs.The MAX15068 is available in a 20-pin, (4mm x 5mm) TQFN package and is specified from a -40°C to +125°C operating temperature range.ApplicationsBaseband StationComputer Systems and ServersRedundant Power SuppliesStorage Bridge BaySupply HoldupTelecom Networks
