Description

The ZXCT1087 is a high side unipolar current sense monitors which eliminates the need to disrupt the ground plane when sensing a load current. The ZXCT1087 has a 40V maximum operating voltage. The wide common-mode input voltage range and low quiescent currents coup°C with SOT25 packages make them suitable for a range of applications; including automotive and systems operating from industrial 24-28V rails. Its quiescent current is only 0.6μA thereby minimizing current sensing error. The ZXCT1087 has fixed gain of 25 voltage output further members of family offers fixed of 50 (ZXCT1085) and current output (ZXCT1083).

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.
