Product details

1. Product overview
The ACS722LLCTR-20AU-T is a linear current sensor developed by Allegro MicroSystems based on Hall effect technology, designed for high-precision, low-noise current measurement. Its core features include:

Range: ±20A DC or AC current detection.

Output characteristics: Analog voltage output (proportional to input current), support fast response (bandwidth typical value 120kHz).

Low power consumption: Operating voltage 4.5V to 5.5V, typical standby current below 1.5mA.

Isolation performance: Built-in electrical isolation, withstand 2.4kV RMS voltage, ensure system safety.

2. Key specifications
Sensitivity: 100mV/A (±20A range).

Accuracy: Typical error ±1.5% (over the whole temperature range).

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

Package: Surface mount SOIC-8 package, compatible with automated production.

3. Typical application scenarios
Industrial automation: motor drive current monitoring, inverter overcurrent protection.

Electric vehicles: Battery management system (BMS), charging pile current detection.

Energy management: Solar inverter, smart meter current measurement.

Consumer electronics: Energy consumption monitoring of high power home appliances (such as air conditioners, refrigerators).

4. Core strengths
High signal-to-noise ratio: Optimized Hall element design reduces temperature drift and noise interference.

Compact package: The SOIC-8 package saves PCB space and is suitable for high-density designs.

No external calibration required: Factory pre-calibration simplifies the system integration process.

5. Frequently Asked Questions (FAQ)
Q1: Can ACS722LLCTR-20AU-T detect AC current?
A: Yes, but an external circuit is required to process AC signals (such as filtering and rectification).

Q2: How to improve the measurement accuracy?
A: Ensure that the supply voltage is stable, and avoid the presence of large current wires or magnetic components near the sensor
