PRECISION HIGH VOLTAGE HIGH-SIDE CURRENT MONITORS

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.

The ZXCT1082/1084/1086 have 60V maximum operating

voltage and ZXCT1083/1085/1087 have 40V maximum

operating voltage.

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 from industrial 24-28V rails.

Their quiescent current is only 0.6µA thereby minimizing

current sensing error.

Typical Application Circuits

R_SENSE

The ZXCT1082 and ZXCT1083 use three external

transconductance/gain setting resistors which increase

versatility by permitting wide gain ranges and optimization of

bandwidths.
