ZXCT1107Q/09Q/10Q
AUTOMOTIVE COMPLIANT MICROPOWER CURRENT MONITOR
Description
Pin Assignments
The ZXCT1107Q/09Q/10Q products 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 and SOT25 packages, make them suitable for a
range of automotive applications.
