MAX15068

Dual ORing, Single Hot-Swap Controller with

Accurate Current Monitoring

General Description

Beneﬁts and Features

● 2.9V to 18V Operating Voltage Range (ORing and

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 circuit-

breaker protection, and power monitoring in a single

package. The device operates on 2.9V to 18V supply

voltages.

Hot Swap)

● Seamless Power Transition of Redundant Supplies

● Controls n-Channel MOSFETs

● < 0.5µs Reverse Turn-Off Time

● Precision Current Monitoring

● Adjustable Slew-Rate Control

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.

● Adjustable Current-Limit Fault Delay

● Adjustable Circuit-Breaker Current Threshold

● Inrush Current Regulated at Startup

● Adjustable Undervoltage Lockout

● Small (4mm x 5mm) TQFN Package

The device implements a foldback current limit during hot-

swap 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, on-

chip 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.

Applications

● Baseband Station

● Redundant Power Supplies

● Supply Holdup

● Computer Systems and Servers

● Telecom Networks

● Storage Bridge Bay

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.
