ZXCT1030 Datasheet, PDF (1/10 Pages) Zetex Semiconductors – HIGH-SIDE CURRENT MONITOR WITH COMPARATOR

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.
Features
• 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
• SO8 package
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.
Applications
• Battery chargers
• Electronic fuse
• DC motor control
• Over current monitor
• Power management
• Inrush current limiting
