Description

The ZXCT1041 is a bidirectional precision high-side current sense monitor. The output voltage is proportional to the differential input voltage. Direction of current flow is indicated by the Flag pin.

The ZXCT1041 provides a fixed gain of 10 for applications where minimal external components are required.

The very low offset voltage enables a typical accuracy of 2 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 2.7V make it suitable for a range of applications.

A minimum operating current of just 40μA, combined with a SOT23-5 package makes the ZXCT1041 particularly suitable for portable battery equipment.
