Product details

1. Product overview
The ACS724LLCTR-20AU-T is a high-performance current sensor chip from Allegro MicroSystems designed for the accurate measurement of DC or AC current. Based on the Hall effect principle, non-invasive current detection is possible without external isolation elements, with a maximum range of ±20A, suitable for industrial and consumer electronics applications in high noise environments.

2. Core features
Range and accuracy: Support ±20A current detection, sensitivity 66mV/A, linear error ±1.5% (full range).

Low power consumption design: operating voltage 3V-5.5V, static current typical value 10mA, suitable for battery powered equipment.

Fast response: Bandwidth 120kHz, step response time 4μs, suitable for high frequency current monitoring (such as motor PWM control).

Integrated protection: Built-in overcurrent detection, reverse power protection and temperature compensation to improve system reliability.

Package and compatibility: SOIC-8 package, compatible with standard PCB layout, support for surface mount process.

3. Typical application scenarios
Industrial automation: motor drive current monitoring, servo system overload protection.

Power management: Current detection of switching power supplies (SMPS) and battery management systems (BMS).

Consumer electronics: Energy consumption monitoring and fault diagnosis of home appliances (such as air conditioners, washing machines).

New energy field: photovoltaic inverter, electric vehicle charging pile current feedback control.

4. Detailed explanation of technical parameters
Electrical characteristics:

Output offset voltage (zero current) : 0.5V (VCC=5V).

Temperature range: -40°C to +125°C, suitable for harsh environments.

Output characteristics: Analog voltage output (proportional to input current), support bidirectional detection.

Anti-interference ability: Internal shield design reduces external magnetic field interference, signal-to-noise ratio (SNR) is better than 60dB.

5. Design considerations
PCB layout optimization: The current path (IP+ to IP-) should be as short and wide as possible to reduce resistance and heat loss.

Filter design: It is recommended to add an RC low-pass filter (such as 1kΩ+100nF) at the output to suppress high-frequency noise.

Temperature compensation: Despite built-in temperature compensation, the output offset needs to be calibrated in extreme temperature environments.

Overcurrent protection: Combined with external comparator to achieve hardware trigger, improve system response speed.
