ZXCT1022
Low offset high-side current monitor
Description
Ordering information
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.
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 25礎, combined with its SOT23-
5 package make it suitable for portable battery
equipment too.
