grated solutions 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.
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, lower-
ing 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 overcur-
rent 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).
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).
The devices are available in a 16-bump, 2mm x 2mm
wafer-level package (WLP) and are rated over the -40°C
to +105°C extended temperature range.

Note 2:
All devices are 100% production tested at T
A
= +25°C. Limits over temperature are guaranteed by design.
Note 3:
41.2kΩ is the maximum allowed external resistance value to be connected at the CB pin to GND for safe operation. All
devices are tested with 10.5kΩ, the parameter specified at R
CB
= 41.2kΩ is guaranteed by bench characterization and cor-
relation, with respect to the tested parameter at R
CB
= 10.5kΩ. The formula that describes the relationship between R
CB
and the circuit-breaker current threshold is: I
CB
= R
CB
/6510)(Ω/A) - 0.34A.
Note 4:
Guaranteed by desing and not production tested.
Note 5:
The current-limit slow-comparator response time is weighed against the amount of overcurrent so the higher the
overcurrent condition, the faster the response time.
Note 6:
Foldback is active during the startup phase so the internal power MOSFET operates within SOA.
