Product Description

The VGA connector does not have a hot-plug pin to tell the system that a monitor is connected. More recent video standards, such as HDMI and DisplayPort, save power by adding a hot-plug pin which allows graphics outputs to be powered down when a monitor is not connected. The PI3VST01 HPD signal generator generates a monitor detection signal from a VGA source connector to tell the VGA source if an external monitor is connected or not. PI3VST01 allows notebook makers to shut off the VGA DAC when a monitor is not connected, thus saving 170 mW per DAC. PI3VST01 dissipates only 0.66 mW. The monitor detection scheme within the PI3VST01 will not affect normal operation of the video driver.
