MAX15095/MAX15095A/
MAX15095D
2.7V to 18V, 6.6A Integrated Hot-Swap/
Electronic Circuit Breaker
General Description
Benefits and Features
The MAX15095 family of devices is an integrated solution
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 breakers for hard
drives, solid-state drives, and fans. The devices integrate
a hot-swap controller (10.6mΩ typ) power MOSFET, and
an electronic circuit-breaker protection in a single pack-
age.
● Integration Reduces Solution Size for Blade Servers
and Other Space-Constrained Designs
• Integrated 10.6mΩ (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
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 can latch off (MAX15095) or automatic retry
(MAX15095A); the output can also be discharged after a
fault event (MAX15095D).

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).
