Product Summary

The BCM5221 includes a unique Intelligent Power-Management feature that powers down the device if energy is not detected on the cable. This feature is especially useful for portable and power-sensitive applications such as laptop LAN card adapters. The BCM5221 allows PCMCIA or CardBus adapters to remain plugged in and draw virtually no energy even if the client is no longer connected to the network. Because most laptop users do not remove their LAN PC card when working remotely, this feature results in a noticeably extended battery life for laptop computer users.
