PRECISION HIGH VOLTAGE HIGH-SIDE CURRENT MONITORS
NEW PRODUCT
Description
Pin Assignments
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.
OUT 1
The ZXCT1082/1084/1086 have 60V maximum operating
voltage and ZXCT1083/1085/1087 have 40V maximum
operating voltage.

VCC
4
S-
GND 2
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.
S+ 3
Their quiescent current is only 0.6µA thereby minimizing
current sensing error.
Typical Application Circuits
RSENSE
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.

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