MAX15096
2.7V to 18V, 6A Integrated
Hot-Swap/Electronic Circuit Breaker
General Description
Benefits and Features
The MAX15096 family of devices are integrated solu-
tions for hot-swap applications requiring the safe
insertion and removal of circuit line cards from a live
backplane. They can also be used as electronics
circuit breaker for hard drive and solid-state drive and
fans. The devices integrate a hot-swap controller, 12mΩ
(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 12mΩ (typ) Internal Power MOSFET
• Programmable Overvoltage Protection and
Undervoltage-Lockout Threshold
• Drive-Present Signal Input (PRSNT pin)
• Thermal Protection
● Flexibility Enables Use in Many Unique Designs
• 2.7V to 18V Operating Voltage Range
• Programmable Inrush Current Control Under SOA
Operation
The devices are designed for protection of 2.7V to 18V
supply voltages. These devices implement a foldback
current limit during startup to control inrush current,
lowering di/dt and keeping 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, PG goes low
and the devices latch off (MAX15096) or automatic retry
(MAX15096A); the output could also be discharged after
a fault event (MAX15096D).
• Adjustable Circuit-Breaker Current/Current-Limit
Threshold
• Programmable Slew-Rate Control
• Variable-Speed Circuit-Breaker Response
• Latchoff (MAX15096) or Automatic Retry
(MAX15096A) Options
● Safety Features Ensure Accurate, Robust Protection
• 6A (max) Load Current Capability
• ±10% Circuit-Breaker Threshold Accuracy
• IN-to-OUT Short-Circuit Detection
• Open-Drain PG Output
• Output Discharge After a Fault Event (MAX15096D Only)
• Programmable Additional Delay (2µs max) to
Fast-Comparator Response Time
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 an under-
voltage/overvoltage input pin (UVOV) that can detect an
undervoltage/overvoltage fault and disconnect the IN from
the OUT. Additional features include internal overtem-
perature protection and a power-good output (PG).
