ZXCT1010
Enhanced high-side current monitor
Description
The ZXCT1010 is a high side current sense
monitor. Using this device eliminates the
need to disrupt the ground plane when
sensing a load current.
It is an enhanced version of the ZXCT1009
offering reduced typical output offset and
improved accuracy at low sense voltage.
Features
• Low cost, accurate high-side current
sensing
• Output voltage scaling
• Up to 2.5V sense voltage
• 2.5V – 20V supply range
• 300nA typical offset current
• 3.5␮A quiescent current
• 1% typical accuracy
• SOT23-5 package
Pinout information
The wide input voltage range of 20V down to as
low as 2.5V make it suitable for a range of
applications. A minimum operating current of
just 4␮A, combined with its SOT23-5 package
make suitable for portable battery equipment.
Applications
• Battery chargers
• Smart battery packs
• DC motor control
• Over current monitor
• Power management
• Programmable current source
