LOW OFFSET HIGH-SIDE CURRENT MONITOR
ZXCT1022
DESCRIPTION
APPLICATIONS
The ZXCT1022 is a precision high side current sense
monitor. Using this type of device eliminates the need
to disrupt the ground plane when sensing a load
current.
The ZXCT1022 provides a fixed gain of 100 for
applications where minimal sense voltage is required.
• Battery chargers
• Smart battery packs
• DC motor control
• Over current monitor
The very low offset voltage enables a typical accuracy
of 3% for sense voltages of only 10mV, giving better
tolerances for small sense resistors necessary at
higher currents.
The wide input voltage range of 20V down to as low as
2.5V make it suitable for a range of applications. With a
minimum operating current of just 25µA, combined
with its SOT23-5 package make it suitable for portable
battery equipment too.
• Power management
• Level translating
• Programmable current source
