ZXCT1109Q Overview

AUTOMOTIVE COMPLIANT MICROPOWER CURRENT MONITOR

ZXCT1107Q/09Q/10Q
AUTOMOTIVE COMPLIANT MICROPOWER CURRENT MONITOR
Description
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.
The device is line powered and as such doesn’t need a separate supply
rail.
Quiescent current is only 3µA, thereby minimizing current sensing error.
One external gain setting resistor increases versatility by permitting
wide gain ranges.
