MAX15090B/MAX15090C

2.7V to 18V, 12A, Hot-Swap Solution

with Current Report Output

General Description

Beneﬁts and Features

The MAX15090B/MAX15090C 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,

6mΩ 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 6mΩ (typ) Internal Power MOSFET

Overvoltage Protection

• Power-Good and Fault Outputs

• Programmable Undervoltage Lockout

• Current Reporting Without Need for External

The devices integrate an accurate current-sense

circuitry and provide 220µA/A of proportional output

current. The devices are designed for protection of 2.7V

to 18V supply voltages.

SENSE

• Thermal Protection

● Flexibility Enables Use in Many Unique Designs

• 2.7V to 18V Operating Voltage Range

• 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)

conditions. After the startup cycle is complete, on-chip

comparators provide VariableSpeed/BiLevel™ protection

against short-circuit and overcurrent faults, and immunity

against system noise and load transients. The load is

disconnected 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 MAX15090B latches off, while the MAX15090C enters

autoretry mode.

• Programmable Slew-Rate Control

• Variable-Speed Circuit-Breaker Response

• Latchoﬀ or Automatic Retry Options

● Safety Features Ensure Accurate, Robust Protection

• 12A (max) Load Current Capability

• ±10% Circuit-Breaker Threshold Accuracy

• Inrush Current Regulated at Startup with Foldback

• Implementation for di/dt Control

• 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

adding an external capacitor. The devices have overvolt-

age/undervoltage input pins that can detect an overvolt-

age/undervoltage fault and disconnect the IN from the

OUT. Additional features include internal overtemperature

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