Overview

The ZXCT1022E5TA is a high-side current sense monitor that converts a high-side differential voltage into a ground-referenced output voltage. It operates over a wide input supply range of 2.5V to 20V while maintaining a low typical quiescent current of 25uA. This device simplifies current measurement by eliminating the need for complex discrete circuits or instrumentation amplifiers in power monitoring applications.

Why Choose This Part

The ZXCT1022E5TA offers a simplified design with a fixed gain that provides a ground-referenced output, reducing external component count. Its low 25uA shutdown current and small SOT23-5 footprint make it ideal for space-constrained, power-sensitive mobile applications. The device maintains +/-3% accuracy across its operating range, ensuring reliable performance without intensive calibration.

Applications

Battery Charger Monitoring
Precisely tracking charge current in portable electronics and battery-powered systems.
Power Management Systems
Implementing over-current protection and power consumption logging in industrial and consumer devices.
Smart Phone and Tablet Power
Measuring current flow from the main battery or USB charging rail into system loads.

Getting Started

To implement this part, place a low-value sense resistor in the high-side supply line and connect the sense terminals to the VIN+ and VIN- pins. Ensure the output is connected to a high-impedance ADC input to maintain measurement accuracy. Since this is a fixed-gain device, refer to the datasheet transfer function to map the ground-referenced output voltage to your measured current.
