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 the ground plane when sensing a load current. and ZXCT1083Q/1085Q/1087Q have 40V VCC 4 S- GND 2 The ZXCT1082Q/1084Q/1086Q have 60V maximum operating voltages 5 maximum S+ 3 operating voltages. 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. Typical Application Circuits Their quiescent current is only 0.6A thereby minimizing current sensing error. The ZXCT1082Q and ZXCT1083Q use three RSENSE VSUPPLY S+ external transconductance/gain setting resistors which increase versatility by VCC permitting wide gain ranges and optimization of bandwidths. The ZXCT1084Q/85Q/86Q/87Q are fixed gain voltage output counterparts of the ZXCT1082Q/83. The ZXCT1082Q/3Q/4Q/5Q/6Q/7Q have been qualified to AEC-Q100 Grade 1 and are Automotive Grade supporting PPAPs.

ZXCT1084Q/85Q/86Q/87Q Voltage output Output pin. Ground pin. This is the positive input of the current monitor. It has a wide common-mode input range. The current through this pin varies with differential sense voltage. An external resistor, RGT, should be connected from S+ to the input side (VSUPPLY) of the sense resistor Should be directly connected to the input side (VSUPPLY) of the sense resistor. This is the negative input of the current monitor. It has a wide common-mode input range. An external resistor, RGT, should be connected from S- to the load side (VLOAD) of the sense resistor. Should be directly connected to the load side (VLOAD) of the sense resistor. This is the analogue supply and provides power to internal circuitry.
