Overview

The ZXCT1010E5TA is a high-side current sense monitor that translates a high-side voltage developed across an external sense resistor into a proportional ground-referenced output voltage. It operates over a wide supply voltage range of 2.5V to 20V and features an extremely low quiescent current of 3.5uA, making it ideal for battery-powered applications.

Why Choose This Part

This monitor offers a high bandwidth of 2MHz, allowing for fast transient detection and high-speed current monitoring. Its SOT25 package and minimal external component requirements save significant PCB real estate while maintaining 1% typical accuracy.

Applications

Battery Charger Monitoring
Tracking charge current in portable electronics and smart battery packs with minimal power overhead.
DC Motor Control
Providing real-time current feedback for torque control and stall detection in small motor drives.
Overcurrent Protection
Acting as a precision front-end for comparator-based safety shutdown circuits in power management systems.
Programmable Current Sources
Integrating into feedback loops to maintain constant current for LED strings or electrochemical processes.

Getting Started

To implement, place a low-value shunt resistor in the high-side supply line and connect the ZXCT1010 across it. Select the output resistor (RG) to scale the output voltage to match your microcontroller ADC input range.

Also Consider

INA219 TITexas Instruments - Offers a digital I2C interface for power, voltage, and current monitoring if an analog output is not preferred.
