Maxim MAX5976AETE+

Контроллер горячей замены1Автоматический повтор, тепловой предел

Overview

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 MAX5976AETE+ 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.
