HIGH-SIDE CURRENT MONITOR WITH COMPARATOR
Description
The   ZXCT1030   is   a   high   side   current   sense   monitor
containing an internal reference and comparator with a non-
latching output. Using this device eliminates the need to
disrupt the ground plane when sensing a load current.
The wide input voltage range of 20V down to as low as 2.2V
make it suitable for a range of applications. Dynamics and
supply current are optimized for the processing of fast pulses,
associated with switch mode applications.
