ENHANCED HIGH-SIDE CURRENT MONITOR
ZXCT1010
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.
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 4µA, combined
with its SOT23-5 package make suitable for portable
battery equipment.
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.
• 4µA quiescent current.
• 1% typical accuracy.
• SOT23 -5 package.
APPLICATIONS
• Battery Chargers
• Smart Battery Packs
• DC Motor control
• Over current monitor
• Power Management
• Level translating
• Programmable current source
