MAX15091/MAX15091A

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

Solution with Current Report Output

General Description

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.

● 2.7V to 18V Operating Voltage Range

● 18mΩ Internal Power MOSFET

● 9A (typ) Load Current Capability

● Analog Current Report Output

● ±10% Circuit-Breaker Threshold Accuracy

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.

● Programmable Inrush Current Control Under SOA

Operation

● Adjustable Circuit-Breaker Current/Current-Limit

Threshold

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.

● Programmable Slew-Rate Control

● Variable-Speed Circuit-Breaker Response

● Thermal Protection

● Overvoltage Protection

● Power-Good and Fault Outputs

● Latch-Off or Automatic Retry Options

● Programmable Undervoltage Lockout

● IN to OUT Short-Circuit Detection

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.

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.
