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

PCB trace shunt resistor for low cost
solution.
The figure below shows output characteristics of the
device when using a PCB resistive trace for a low
cost solution in replacement for a conventional
shunt resistor. The graph shows the linear rise in
voltage across the resistor due to the PTC of the
material and demonstrates how this rise in
resistance value over temperature compensates for
the NTC of the device.
The figure opposite shows a PCB layout suggestion.
The resistor section is 25mm x 0.25mm giving
approximately 150mΩ using 1oz copper. The data
for the normalised graph was obtained using a 1A
load current and a 100Ω output resistor. An
electronic version of the PCB layout is available at
