The ZXCT1009F is a high side current sense monitor in 3 pin SOT-23 package. This device eliminates the need to disrupt ground plane when sensing load current. It takes high side voltage developed across current shunt resistor and translates it into a proportional output current. A user defined output resistor scales the output current into a ground referenced voltage.
