ACS714ELCTR-05B-T

Current Sensors Overview

The Allegro MicroSystems ACS714ELCTR-05B-T is a Hall effect-based open-loop current sensor IC designed for precise AC and DC current measurement. It features a 5A bidirectional detection range with a sensitivity of 185mV/A and an accuracy of ±1.5%. Operating on a 5V supply, it delivers a proportional voltage output through an 8-SOIC package. The device supports frequencies up to 80kHz with a response time of 3.5µs, functioning within a -40°C to 85°C temperature range while consuming a maximum supply current of 13mA.

Current Sensors Feature Summary

• Provides galvanic isolation between the high-current conduction path and the signal output circuitry using integrated copper leads.
• Delivers a linear analog voltage output proportional to the sensed current for direct interfacing with microcontrollers or ADCs.
• Integrates low-offset chopper-stabilized Hall sensors and amplifiers to ensure accurate sensing across the operating temperature range.

Current Sensors Applications

• Motor control systems in automotive applications
• General-purpose current monitoring in industrial equipment
• Overcurrent protection circuits requiring fast response times

Current Sensors Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm the specific suffix matches the required current rating and package variant. Ensure storage conditions comply with Moisture Sensitivity Level 2 requirements to prevent package damage prior to reflow soldering.

Current Sensors Selection Notes

Select this model when a compact surface-mount solution is required for bidirectional current sensing up to 5A. Consider the 185mV/A sensitivity and 80kHz bandwidth for applications demanding rapid transient detection. Evaluate thermal management needs as the internal copper path generates heat proportional to the load current.
