MAX15090/MAX15090A
2.7V to 18V, 12A, Hot-Swap Solution
with Current Report Output
General Description
The MAX15090/MAX15090A 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.
The devices integrate an accurate current-sense circuitry
and provide 220FA/A of proportional output current.
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 keep
the MOSFET operating under safe operating area (SOA)
conditions. After the startup cycle is complete, on-chip
comparators
provide
VariableSpeed/BiLevelK
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
Q10%
accuracy. During a fault
condition, the MAX15090 latches off, while the MAX15090A
enters autoretry mode.
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
overvoltage/undervoltage input pins that can detect an
overvoltage/undervoltage fault and disconnect the IN
from the OUT. Additional features include internal over-
temperature protection, power-good output, and fault-
indicator output.
The MAX15090/MAX15090A are available in a 28-bump,
2.07mm x 3.53mm, power wafer-level package (WLP)
and are rated over the -40°C to +85°C extended
temperature range.
