SEMICO NDUC TORS

DESCRIPTION

The ZXCT1021 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 ZXCT1021 provides a fixed gain of 10 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 25µA, combined

with its SOT23-5 package make it suitable for portable

battery equipment too.
