Description

The ZXCT1107/09/10 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 coup°C with SOT23 packages make them suitable for a range of applications; including adapters, automotive and systems operating from industrial 24 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.

Application(s)

  • Automotive current monitoring
  • Industrial current monitoring

    Feature(s)

  • High accuracy current measurement: o improved system precision
  • Simple to use: o low external component count
  • High side monitoring: o no disruption of ground plane
  • Low quiescent current (3uA): o high efficiency
  • Wide common mode range (2.5V to 36V): o suitable for automotive and industrial applications with supplies up to 36V

    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.
