The ZXCT1021 and ZXCT1022 are voltage output current
monitors, with fixed gain scaling.
V
The output is scaled internally by 10 on the ZXCT1021 and 100
on the ZXCT1022. This scaling allows low value sense
resistors to be used, thus reducing power dissipation and
voltage drop. The ZXCT1021 and ZXCT1022 are pin compatible
with the ZXCT1010, which provides an easy upgrade path for
improved performance.
The ZXCT1030 is a voltage output current monitor with fixed
gain scaling of 10. A non-latching output comparator and 1.24V
voltage reference are also included on-chip to make more
integrated solutions possible. Operating voltage range is 2.2V
to 20V and quiescent current is only 270µA. A separate V cc
supply ensures the device gives an output under short circuit
conditions. When the V
the comparator defaults to the asserted state. By feeding
reference output to the comparator input a simple and compact
over-current protection circuit can be developed.
The ZXCT1041 is a bidirectional voltage output current monitor
with direction flag. The flag is an open collector output enabling
it to be coupled to a wide range of logic level voltages.
The voltage output pin is analog and is internally scaled to 10
times V
enabling it to work in a wide range of applications including
automotive, motor control and battery gas-gauging. Apart from
its flag output the ZXCT1041 is pin compatible to the ZXCT1021.
The ZXCT1051 is a wide common-mode range voltage output
current monitor designed to measure at voltages ranging from
under supply to ground. This makes the device suitable for
systems which need to function under short circuit conditions.
An auxiliary power supply is required to feed the device and
keep the internal circuitry active. V cc range is 20V to 3V and
V
performance is similar to the ZXCT1021, with internal gain
setting of 10.
The ZXCT1081 has a wide continuous common-mode input
range from 3V to 40V (60V transient). The ZXCT1080 extends
the continuous common mode range to 60V. This allows it to
measure currents in a wide range of applications ranging from
computer power supplies to automotive.
A separate power supply pin provides power to an internal
buffer lowering the output impedance
The ZXCT1032 provides in-rush current limiting and over
current protection functions and when used with an external
P-MOSFET behaves as an electronic fuse. At power up the load
current is gradually increased; protecting input power supply
from large capacitive loads. In over-current protection mode the
device is transparent; just measuring the output current. When
the over-current threshold is exceeded the device switches off
the MOSFET protecting both the load and supply rail from
damage. The ZXCT1032 will auto retry.
