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.

Caution:
Stresses greater than the 'Absolute Maximum Ratings' specified above, may cause permanent damage to the device. These are stress ratings only;
functional operation of the device at these or any other conditions exceeding those indicated in this specification is not implied. Device reliability may be
affected by exposure to absolute maximum rating conditions for extended periods of time.
Semiconductor devices are ESD sensitive and may be damaged by exposure to ESD events. Suitable ESD precautions should be taken when handling
and transporting these devices.

7. VIO is extrapolated from measurements for the gain-error test.
8. For VSENSE > 10mV, the internal voltage-current converter is fully linear. This enables a true offset to be defined and used.
9. Gain or transconductance error is calculated by applying two values of VSENSE and calculating the error of the slope vs. the ideal.
