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 counterparts of the ZXCT1082/3. gain voltage output
