Overview

The ACS724LLCTR-10AU-T is a high-accuracy, unidirectional Hall effect-based current sensor designed for DC measurement up to 10A. It features a compact SOIC-8 footprint with an integrated low-resistance primary conductor, providing 2.4kV RMS isolation and a high-bandwidth 120kHz analog output.

Why Choose This Part

This sensor offers an industry-leading 1 percent accuracy and 400mV/A sensitivity through integrated digital temperature compensation. Its differential Hall sensing technology provides high immunity to stray magnetic fields, while the 120kHz bandwidth allows for high-speed switching applications.

Applications

Automotive Auxiliary Systems
AEC-Q100 qualification makes it suitable for monitoring small motors and electronic control units in vehicles.
DC-DC Converters
Provides high-speed current feedback for power supply regulation with a fast 4us response time.
Solar Inverter Monitoring
Ideal for tracking unidirectional current flow from photovoltaic panels into battery storage or conversion stages.
Industrial Load Detection
Used in factory automation for real-time monitoring of DC actuators and industrial control loops.

Getting Started

Connect the primary current path to pins 1/2 and 3/4, then provide a stable 5V supply to the VCC pin. The FILTER pin can be used to set the bandwidth with an external capacitor to improve signal-to-noise ratio in slower applications. Ensure the PCB layout includes sufficient copper area around the current pins to manage thermal dissipation.
