PRECISION HIGH VOLTAGE HIGH-SIDE CURRENT MONITORS
Description
The ZXCT1082 and ZXCT1083 are high side unipolar
current sense monitors. These devices eliminate the need to
disrupt the ground plane when sensing a load current.
The ZXCT1082/1084/1086 have 60V maximum operating
voltage and ZXCT1083/1085/1087 have 40V maximum
operating voltage.
The wide common-mode input voltage range and low
quiescent currents coupled with SOT25 packages make
them suitable for a range of applications; including
automotive and systems operating from industrial 24-28V
rails.
Their quiescent current is only 0.6µA thereby minimizing
current sensing error.
The ZXCT1082 and ZXCT1083 use three external
transconductance/gain setting resistors which increase
versatility by permitting wide gain ranges and optimization of
bandwidths.
The ZXCT1084/5/6/7 are fixed gain voltage output
counterparts of the ZXCT1082/3.
