The MAX5976A/MAX5976B 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, 24mI power
MOSFET, and electronic circuit-breaker protection in a
single package. The ICs are designed for protection of
2.7V to 18V supply voltages.
The devices provide inrush current control and short-
circuit detection during startup. During normal operation,
the devices provide circuit-breaker protection against
overload and short-circuit conditions. The
function disconnects the power to the load if the load
current exceeds the circuit-breaker limit.
are factory-calibrated to deliver accurate overcurrent
protection with Q10% accuracy. During a fault condi-
tion, the MAX5976A enters an autoretry mode while the
MAX5976B latches off. Both versions feature a resistor-
adjustable variable speed circuit-breaker threshold and
overtemperature protection. Additional features include
power-good and fault indicator outputs.
The ICs are available in a 16-pin, 5mm x 5mm, TQFN-
EP package and fully specified over the -40
operating temperature range.
