2.7V to 18V, 7A, Hot-Swap Solution
General Description
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, 24m I 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 circuit-breaker
function disconnects the power to the load if the load
current exceeds the circuit-breaker limit. The devices
are factory-calibrated to deliver accurate overcurrent
protection with Q 10% 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.
