ACS712 SMD IC Hall Current Sensor Module 20A XBLW SOP8 SOIC8 ACS712ELCTR-20A-T(XBLW)

Product Overview:

A high-performance, integrated Hall-effect current sensor designed for precise measurement of both AC (Alternating Current) and DC (Direct Current) applications. By utilizing internal low-resistance conductor pathways and highly sensitive linear Hall-effect circuitry, the device converts flowing current into a proportional voltage output while maintaining robust galvanic isolation between the primary current path and the secondary control electronics.

Core Specifications:

Manufacturer: XINBOLE (艾伯乐)

Package Type: SOP8 (Surface Mount)

Function: Hall-Effect Linear Current Sensor

Input Channels: 1 Primary High-Current Input Path (Internal to the IC)

Control Interface: Analog Voltage Output (VOUT) proportional to the input current

Features

• High Versatility: Capable of sensing both AC and DC signals with high linearity and accuracy across industrial, consumer, and communication hardware platforms.

• Integrated Sensing Architecture: Houses a low-impedance copper conduction path and a high-precision Hall-effect sensor within a single, compact monolithic package.

• Advanced Internal Signal Processing: Features BCDMOS fabrication including an integrated Hall sensor, pre-amplifier, temperature compensation unit, oscillator, and dynamic offset cancellation circuitry to ensure stable performance.

• Proportional Analog Output: In a 5V power environment, the static output voltage is typically fixed at 2.5V (or 50% of Vcc), varying linearly between 0.2V and 4.8V based on the measured magnetic field generated by the input current.

• High Stability: Internal dynamic offset cancellation circuitry effectively mitigates output drift caused by mechanical stress or external environmental factors.

• Extended Temperature Range: Rated for reliable operation in harsh environments, spanning from -40°C to +150°C.

Applications

• Industrial Motor Drives: Monitors phase currents for precise control and protection of AC induction and brushless DC motors.

• Power Conversion and Management: Tracks input and output current metrics in high-efficiency DC-to-DC converters and power supply units.

• Automotive Systems: Measures current for battery monitoring, alternator management, and auxiliary electronic load tracking.

• Consumer Electronics: Regulates and monitors current levels in smart home power strips and intelligent appliances.

• Renewable Energy Systems: Acts as the current sensing node for solar inverter strings and wind turbine output power logging.
