ZXCT1082Q/83Q/84Q/85Q/86Q/87Q
AUTOMOTIVE GRADE PRECISION HIGH VOLTAGE HIGH-SIDE CURRENT MONITORS
Description
The ZXCT1082Q/83Q/84Q/85Q/86Q/87Q are high side unipolar
current sense monitors. These devices eliminate the need to disrupt
the ground plane when sensing a load current.
The ZXCT1082Q/1084Q/1086Q have 60V maximum operating
voltages and ZXCT1083Q/1085Q/1087Q have 40V maximum
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.
Their quiescent current is only 0.6µA thereby minimizing current
sensing error.
The ZXCT1082Q and ZXCT1083Q use three external
transconductance/gain setting resistors which increase versatility by
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.

Notes:
1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS) & 2011/65/EU (RoHS 2) compliant.
2. See http://www.diodes.com/quality/lead_free.html for more information about Diodes Incorporated’s definitions of Halogen- and Antimony-free, "Green"
and Lead-free.
3. Halogen- and Antimony-free "Green” products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl) and
<1000ppm antimony compounds.
4. Automotive products are AEC-Q100 qualified and are PPAP capable. Automotive, AEC-Q100 and standard products are electrically and thermally
the same, except where specified. For more information, please refer to http://www.diodes.com/quality/product_compliance_definitions.
