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, 24mΩ 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 ±10% accuracy. During a fault condition, 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°C to +85°C operating temperature range.

Product Details

The MAX5976B evaluation kit (EV kit) provides a proven design to evaluate the MAX5976B hot-swap controller with an integrated 7A MOSFET. The EV kit is configured to pass 7A into a 2.7V to 18V hot-swap application, thus providing a fully integrated solution. The EV kit uses the MAX5976BETE+ in a 5mm x 5mm x 0.8mm, 16-pin TQFN package on a proven four-layer PCB design.

The EV kit can also be used to evaluate the MAX5976A after IC replacement of U1.
