The ZXCT1107SA-7 is a Low Power High-side Current Monitor that eliminate the need to disrupt the ground plane when sensing a load current. The wide common-mode input voltage range and low quiescent current make it suitable for a range of applications, including adapters, automotive and systems operating from industrial 24V rails. The device is line powered and as such doesn't need a separate supply rail. Quiescent current is only 3μA thereby minimising current sensing error. One external gain setting resistor increases versatility by permitting wide gain ranges.
