The ZXCT1021E5TA is a Low Offset High-side Current Monitor used to eliminate the need to disrupt the ground plane when sensing a load current. It 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. A minimum operating current of just 25µA make it suitable for portable battery equipment too.
