Features
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
Typical Application Circuit
ZXCT1030
Document number: DS32161 Rev. 4 - 2
Low cost, accurate high-side current sensing
Output voltage scaling
Up to 18V output
2.2V - 20V supply range
Voltage reference on chip
Comparator on chip
