| PI3VST01 HPD signal Generator for VGA Plug Detect Signal Generator for VGA connectors hot plug output signal telling system when monitor is present or not Supply, 3.3V and 5.0V tolerance on pin 7 is up to +/-4kV contact per IEC61000-4-2 specification BW of 1.7GHz typ Ohm On Resistance with Ohm flatness typ input/output capacitance Con = 4.5pF, typ Pb-free and Green : àà 8-contact MSOP U àà 10-contact TDFN ZE 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. Pericom’s 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 mW. The monitor detection scheme within the PI3VST01 will not affect normal operation of the video driver.
