The ZXCT1080Q and ZXCT1081Q are high side current sense monitors with a voltage output and a fixed gain of 10. Using this device eliminates the need to disrupt the ground plane when sensing a load current.
The wide input voltage range of 60V and 40V, respectively, down to as low as 3V make it suitable for a range of automotive applications with 60V and 40V load dump withstand capabilities.
The separate supply pin (VCC) allows the device to continue functioning under short circuit conditions.
The ZXCT1080Q and ZXCT1081Q have an extended ambient operating temperature range of -40°C to 125°C enabling it to be used in a wide range of automotive applications including.
The ZXCT1080Q and ZXCT1081Q 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.
