Product details

I. Product overview
ACS724LLCTR-30AU-T is a linear current sensor chip designed by Allegro MicroSystems based on the Hall effect principle, designed for high-precision current detection and system protection needs. Its core advantages include:

Wide range detection: Support ±30A AC or DC current measurement, suitable for high-power scenarios.

Low noise output: internal integrated filter circuit, output signal noise as low as 20mV (typical value), improve system stability.

Fast response: Bandwidth up to 120kHz, can capture instantaneous current changes, suitable for dynamic load monitoring.

Isolation design: Electrical isolation of current path and signal circuit to enhance system safety.

2. Key specification parameters
Power supply voltage: 3.0V to 5.5V, compatible with a variety of power systems.

Output voltage: 0.5V to 4.5V (proportional output, corresponding to ±30A linear range).

Sensitivity: 40mV/A (typical value), support high resolution current detection.

Operating temperature: -40°C to +125°C, suitable for harsh industrial environments.

Package type: Surface mount SOIC-8 package for easy integration into PCB design.

3. Core application scenarios
Industrial automation

Motor drive system: real-time monitoring of motor current, overload protection and energy efficiency optimization.

Robot control: precise feedback of joint current to improve motion control accuracy.

Power management system

Battery charge and discharge monitoring: Prevent the risk of overcurrent/short circuit and extend battery life.

Photovoltaic inverter: Optimize energy conversion efficiency to ensure safe operation of the system.

Consumer electronics and home appliances

Intelligent home appliances: such as air conditioning, refrigerator current anomaly detection, enhance equipment reliability.

Automotive electronics

In-vehicle Charger (OBC) : Monitors high voltage current and meets functional safety standards (such as ISO 26262).

4. Design advantages and precautions
Integrated solution: Built-in temperature compensation and reverse voltage protection to reduce the need for external components.

Overcurrent detection function: The external comparator quickly triggers the protection mechanism (such as cutting off the power supply).

Layout Suggestions:

Avoid strong magnetic field interference sources near the sensor.

The current path routing must meet the current carrying capacity (for example, copper thickness ≥2oz).
