ZXCT1030
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 optimised for the
processing of fast pulses, associated with switch mode
applications.
