Descriptions:

The ACS712ELCTR-05B-T is a fully integrated, Hall-effect-based linear current sensor that provides precise current sensing for AC or DC applications. It features a low-resistance current path for minimal power loss and electrical isolation from the sensed current. The output voltage is proportional to the input current, with a quiescent output voltage at half the supply voltage (2.5V at 5V VCC).

Features:

• Low-noise analog signal path
• Factory-trimmed for accuracy
• Fast response time (<5 μs)
• Overcurrent fault detection (OCD) capability
• Ratiometric output from supply voltage
• High isolation voltage (2.1 kV RMS)
• Small footprint (SOIC-8 package)
• Suitable for motor control, power supplies, and battery management applications

This sensor is commonly used in industrial, automotive, and consumer electronics for current monitoring and protection.
