The ZXCT1022 is a precision high-side current sense monitor. Using this type of device eliminates the need to disrupt the ground plane when sensing a load current. The ZXCT1022 provides a fixed gain of 100 for applications where minimal sense voltage is required. The very low offset voltage enables a typical accuracy of 3% for sense voltages of only 10mV, giving better tolerances for small sense resistors necessary at higher currents. The wide input voltage range of 20V down to as low as 2.5V make it suitable for a range of applications. With a minimum operating current of just 25μA, combined with its SOT25 package make it suitable for portable battery equipment too.

    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.
