VGA通讯接口静电保护方案。
In most of VGA input circuit designs, there are always two power supplies, one is from the connector’s DSUB-5V pin which potential comes from another VGA output port, the other is from the own power supply circuit of the VGA input port, system 5V. The VDD pin ofESDSRVLC05-4 is directly connected to the connector’s DSUB-5V pin to block the ESD event which comes from the DSUB-5V pin.
