詳細說明
The Allegro® ACS712 provides economical and precise solutions for AC or DC current sensing in industrial, commercial, and communications systems. The device package allows for easy implementation by the customer. Typical applications include motor control, load detection and management, switch mode power supplies, and overcurrent fault protection. The device is not intended for automotive applications.The device consists of a precise, low-offset, linear Hall circuit with a copper conduction path located near the surface of the die. Applied current flowing through this copper conduction path generates a magnetic field which the Hall IC converts into a proportional voltage. Device accuracy is optimized through the close proximity of the magnetic signal to the Hall transducer. A precise, proportional voltage is provided by the low-offset, chopper-stabilized BiCMOS Hall IC, which is programmed for accuracy after packaging.Features and Benefits▪ Low-noise analog signal path▪ Device bandwidth is set via the new FILTER pin▪ 5 μs output rise time in response to step input current▪ 80 kHz bandwidth▪ Total output error 1.5% at TA= 25°C▪ Small footprint, low-profile SOIC8 package▪ 1.2 mΩ internal conductor resistance▪ 2.1 kVRMS minimum isolation voltage from pins 1-4 to pins 5-8▪ 5.0 V, single supply operation▪ 66 to 185 mV/A output sensitivity▪ Output voltage proportional to AC or DC currents▪ Factory-trimmed for accuracy▪ Extremely stable output offset voltage▪ Nearly zero magnetic hysteresis▪ Ratiometric output from supply voltage

常見問題解答
What is ACS712ELCTR-05B?
The ACS712ELCTR-05B is a fully integrated, hall-effect-based linear current sensor IC (integrated circuit) designed by Allegro MicroSystems. It provides an economical and precise solution for AC or DC current sensing in industrial, commercial, and communications systems.
How Does ACS712ELCTR-05B Work?
The ACS712ELCTR-05B works by utilizing the principle of the hall effect to measure current passing through a conductor. When current flows through the sensor, it generates a magnetic field that is sensed by the internal hall-effect sensor. The output of the sensor is proportional to the current passing through, providing an accurate representation of the measured current.
How Many Pins does ACS712ELCTR-05B have and What are the Functions of the Pinout Configuration?
The ACS712ELCTR-05B is housed in an 8-lead SOIC (Small Outline Integrated Circuit) package. The pinout configuration includes:
- VCC: Power supply pin.
- OUT: Output pin for the sensed current.
- GND: Ground pin.
- IP+/IP-: Pins for connecting the current-carrying conductor.
What are the Pros and Cons of ACS712ELCTR-05B?
Pros:
- High Accuracy: Provides accurate current sensing for precise measurements.
- Wide Sensing Range: Supports both AC and DC current sensing up to ±5A.
- Low-Noise Output: Offers a low-noise output signal for reliable measurements.
- Integrated Solution: Fully integrated sensor IC simplifies the design and implementation process.
- High Bandwidth: Suitable for applications requiring fast response to changes in current.
Cons:
- Temperature Sensitivity: The sensor output may be sensitive to temperature variations.
- External Components: May require additional external components for signal conditioning or protection.
Are There Any Equivalents/Alternatives to ACS712ELCTR-05B for Recommendation?
- The ACS711 from Allegro MicroSystems is a family of current sensor ICs with different current rating options.
- Alternatives to the ACS712ELCTR-05B include the ZMCT103C from ZMCT and the INA219 from Texas Instruments.
