The ZXCT1107Q/09Q/10Q are high side unipolar current sense monitors. These devices eliminate the need to disrupt the ground plane when sensing a load current. 
The wide common-mode input voltage range and low quiescent current coupled with SOT23 packages make them suitable for a range of automotive applications. 
The device is line powered and as such doesn’t need a separate supply rail. 
Quiescent current is only 3µA thereby minimizing current sensing error. One external gain setting resistor increases versatility by permitting wide gain ranges. 
The ZXCT1107Q/09Q/10Q have been qualified to AEC-Q100 Grade 1 and are Automotive Grade supporting PPAPs.

Diodes Incorporated's current monitors are high-performance, high-side/power rail current measurement ICs. They greatly simplify the measurement of load currents without disturbing the ground plane/reference point.

The current monitor families contain variants with quiescent currents as low as 3µA, and others with operating voltages up to 60V, proving solutions for overcurrent detection in consumer, industrial, and automotive applications. The portfolio includes current output variants which via an external resistor to ground to provide adjustable gain, and voltage output variants with fixed gains.

Automotive-compliant variants are available which are qualified to AEC-Q100 Grade 1 in IATF 16949 facilities supporting PPAP documentation.
