The ZXCT1011 is a high side current sense monitor. Using this type of device eliminates the need to disrupt the ground plane when sensing a load current. The ZXCT1011 takes the voltage developed across a current shunt resistor and translates it into a proportional output current. A user defined output resistor scales the output current into a ground referenc.
