General Description

The MAX15096/MAX15096A/MAX15096D ICs are inte-

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.
