MAX3218 1µA Supply Current, 1.8V to 4.25V-Powered RS-232 Transceiver with AutoShutdown™ _______________General Description

... A 1µA supply current is achieved with Maxim’s new AutoShutdown feature, which operates when FORCEON is low and FORCEOFF is high. When the MAX3218 senses no valid signal level on either receiver input for typically 30µs, the on-board power supply and drivers shut down, reducing supply current to 1µA. ...

Islanding

Islanding refers to the condition in which a distributed generator (DG) continues to power a location even though electrical grid power from the electric utility is no longer present. Islanding can be dangerous to utility workers, who may not realize that a circuit is still powered, and it may prevent automatic re-connection of devices. For that reason, distributed generators must detect islanding and immediately stop producing power; this is referred to as anti-islanding.The common example of islanding is a grid supply line that has solar panels attached to it. In the case of a blackout, the solar panels will continue to deliver power as long as irradiance is sufficient. In this case, the supply line becomes an ""island"" with power surrounded by a ""sea"" of unpowered lines. For this reason, solar inverters that are designed to supply power to the grid are generally required to have some sort of automatic anti-islanding circuitry in them.In intentional islanding, the generator disconnects from the grid, and forces the distributed generator to power the local circuit. This is often used as a power backup system for buildings that normally sell their excess power to the grid.
