ACS712ELCTR-05B-T** is a Hall-effect-based linear current sensor manufactured by **Allegro MicroSystems**.

The ACS712ELCTR-05B-T is a Hall-effect-based linear current sensor manufactured by Allegro MicroSystems.

Specifications:

  • Manufacturer: Allegro MicroSystems
  • Model: ACS712ELCTR-05B-T
  • Current Sensing Range: ±5A
  • Sensitivity: 185 mV/A
  • Output Voltage: 2.5V (at 0A)
  • Supply Voltage (VCC): 4.5V to 5.5V
  • Operating Temperature Range: -40°C to +85°C
  • Package: SOIC-8
  • Output Type: Analog Voltage (ratiometric to supply voltage)
  • Bandwidth: 80 kHz
  • Isolation Voltage: 2.1 kV RMS
  • Low Resistance Conductor: 1.2 mΩ (internal current path)

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.
