HIGH-SIDE CURRENT MONITOR WITH COMPARATOR
ZXCT1030
DESCRIPTION
APPLICATIONS
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.
• Battery chargers
• Electronic fuse
• DC motor control
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.
• Over current monitor
• Power management
• Inrush current limiting
FEATURES
• Low cost, accurate high-side current sensing.
• Output voltage scaling.
• Up to 18V output.
• 2.2V – 20V supply range.
• 270␮A quiescent current.
• 1.5% typical accuracy.
• MSOP8 Package.
• Voltage reference on chip
• Comparator on chip
