Overview

19-5542; Rev 1; 4/11 EVAALVUAAILTAIOBNLEKIT 2.
7V to 18V, 7A, Hot-Swap Solution MAX5976A/MAX5976B 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, 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 shortcircuit 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 Q10% accuracy.
During a fault condition, the MAX5976A enters an autoretry mode while the MAX5976B latches off.
Both versions feature a resistoradjustable 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, TQFNEP package and fully specified over the -40°C to +85°C operating temperature range.
