Description
Features
Applications
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 coupled with SOT23 packages make
them suitable for a range of applications; including
adapters, automotive and systems operating from industrial
24V 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.
