MAX15091/MAX15091A

2.7V to 18V, 9A, Integrated Hot-Swap

Solution with Current Report Output

General Description

Beneﬁts and Features

The MAX15091/MAX15091A ICs are integrated solutions

for hot-swap applications requiring the safe insertion and

removal of circuit line cards from a live backplane. The

devices integrate a hot-swap controller, 18mΩ (typ) power

MOSFET, and an electronic circuit-breaker protection in a

single package.

● Integration Reduces Solution Size for Blade Servers

and Other Space-Constrained Designs

• Integrated 18mΩ (typ) Internal Power MOSFET

• Overvoltage Protection

• Power-Good and Fault Outputs

• Analog Current Report Output without Need for

External R

• Thermal Protection

SENSE

The devices integrate an accurate current-sense circuitry

and provide 170µA/A of proportional output current. The

devices are designed for protection of 2.7V to 18V supply

voltages.

● Flexibility Enables Use in Many Unique Designs

• 2.7V to 18V Operating Voltage Range

• Programmable Inrush Current Control Under SOA

Operation

These devices implement a foldback current limit during

startup to control inrush current lowering di/dt and keep the

MOSFET operating under safe operating area (SOA) con-

ditions.After the startup cycle is complete, on-chip compar-

ators provide VariableSpeed/BiLevel™ protection against

short-circuit and overcurrent faults, and immunity against

system noise and load transients. The load is disconnect-

ed in the event of a fault condition. The devices are factory

calibrated to deliver accurate overcurrent protection with

±10% accuracy. During a fault condition, the MAX15091

latches off, while the MAX15091A enters autoretry mode.

• Adjustable Circuit-Breaker Current/Current-Limit

Threshold

• Programmable Slew-Rate Control

• Programmable Undervoltage Lockout

• Variable-Speed Circuit-Breaker Response

• Latchoff or Automatic Retry Options

● Safety Features Ensure Accurate, Robust Protection

• 9A (max) Load Current Capability

• ±10% Circuit-Breaker Threshold Accuracy

• Inrush Current Regulated at Startup with Foldback

• Implementation for di/dt Control

The devices feature an IN to OUT short-circuit detection

before startup. The devices provide a power-MOSFET

GATE pin to program the slew rate during startup by add-

ing an external capacitor. The devices have overvoltage/

undervoltage input pins that can detect an overvoltage/

undervoltage fault and disconnect the IN from the OUT.

Additional features include internal overtemperature pro-

tection, power-good output, and fault-indicator output.

• IN-to-OUT Short-Circuit Detection

Applications

● Blade Servers

● Server I/O Cards

● RAID Systems

● Disk Drive Power

● Storage Applications

● Industrial Applications

The MAX15091/MAX15091A are available in a 28-pin,

5mm x 5mm TQFN power package and are rated over the

-40°C to +85°C extended temperature range.
