Pin Description
PIN Name
Description
Common ZXCT1082/3 ZXCT1084/5/6/7
1 OUT Output pin. Current output. Voltage output
2 GND Ground pin.
3 S+
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, R
GT
, should
be connected from S+ to the input
side (V
SUPPLY
) of the sense
resistor
Should be directly connected to
the input side (V
SUPPLY
) of the
sense resistor.
4 S-
This is the negative input of the
current monitor. It has a wide
common-mode input range.
An external resistor, R
GT
, should
be connected from S- to the load
side (V
LOAD
) of the sense resistor.
Should be directly connected to
the load side (V
LOAD
) of the sense
resistor.

CC
This is the analogue supply and provides power to internal circuitry.

Operation above the absolute maximum rating may cause device failure. Operation at the absolute maximum ratings, for
extended periods, may reduce device reliability.
