A Product Line of Diodes Incorporated ZXCT1082Q/83Q/84Q/85Q/86Q/87Q AUTOMOTIVE GRADE PRECISION HIGH VOLTAGE HIGH-SIDE CURRENT MONITORS Description Pin Assignments The ZXCT1082Q/83Q/84Q/85Q/86Q/87Q are high side unipolar current sense monitors. These devices eliminate the need to disrupt OUT 1 V 5 CC the ground plane when sensing a load current. GND 2 The ZXCT1082Q/1084Q/1086Q have 60V maximum operating voltages and ZXCT1083Q/1085Q/1087Q have 40V maximum operating voltages. S+34 S- 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 Typical Application Circuits from industrial 24-28V rails. R SENSE Their quiescent current is only 0.6A thereby minimizing current V V SUPPLY LOAD sensing error. S+ S- The ZXCT1082Q and ZXCT1083Q use three external ZXCT1084/1085 transconductance/gain setting resistors which increase versatility by permitting wide gain ranges and optimization of bandwidths.
