Description
Key features include high accuracy and reliability, with a low-noise analog signal path, and it operates over a broad temperature range. The device employs a Hall-effect principle to measure the magnetic field generated by the current passing through an internal conductor, thus providing electrical isolation between the measured current and the sensing element. This makes it suitable for applications like motor control, power supply monitoring, and overcurrent fault protection. The ACS712ELCTR-30A-T is favored in projects where precise current measurement is crucial while maintaining safety and simplicity in circuit design.

- Output: Provides an analog voltage output proportional to the sensed current.
- Bandwidth: The bandwidth is typically around 80 kHz.
- Accuracy: Provides a precise and linear output over the operating range.
- Response Time: Fast response time of 5 μs, suitable for dynamic or transient current monitoring.
- Operating Temperature: Range from -40°C to 85°C.
- Package: Comes in a small, surface-mount SOIC-8 package.
- Applications: Ideal for motor control, load detection, over-current fault protection, and power management systems.
These features make it suitable for incorporating into a wide range of industrial and consumer applications for reliable current measurement.
Pinout
1. VCC (Pin 1): Supply voltage, typically 5V.
2. Output (Pin 2): Provides the analog voltage output proportional to the current passing through the sensor.
3. GND (Pin 3): Ground reference for the sensor.
4. IP+ (Pins 4, 5): Positive current input; current flows into this terminal.
5. IP- (Pins 6, 7): Negative current input; current flows out of this terminal.
6. NC (Pin 8): No connection.
The device measures current up to ±30A and outputs an analog voltage centered at VCC/2 when there is no current (0A). The sensitivity for the 30A version is typically 66mV/A. It is widely used for current sensing in power supplies, motor control, and other applications requiring precise current measurement.
