In our offer there is also a separate chip: ACS711KLCTR.

Description

The module consists of a printed circuit Board made for the system Allegro ACS711KLCTR-25AB-T. The sensor operates based on the Hall effect. The chip can be powered from voltage range: 3.0 V to 5.5 V. is Characterized by a sensitivity of 55 mV/A when powered at 3.3 V and 84 mV/A at 5 V.

 

Basic module features:

  • The layout is designed for current flowing in both directions (from -25 to 2 5A)
  • Thanks nieskiej resistance of the system (1.2 m Ohm) and wire the power loss is very small.
  • Through the use of Hall effect current paths are isolated from the parts of the puzzle.
  • The frequency range of 100 kHz.
  • The accuracy of the order of 5% at room temperature.
  • The FAULT output is translated into a low state when the current exceeds the allowable range of +/- 2 5A

The sensor requires a supply voltage of 3V - 5.5 V, which is indicated on pin Vcc. The output of the sensor (pin - OUT)- voltage analogue centering value VCC/2. When powered from 3.3 V the output voltage is changed to 55mV at 1A of measured current. The positive direction of the current is increased the value of the voltage is negative, on the contrary, decreases.

The pattern on the output voltage VOUT switches as follows:

 

VOUT = (0.055 V/A * i + 1.65 V) * Vcc / 3.3 V

Pin FAULT, usually in a state of high reaches in the low state when the measured current exceeds the allowable range of +/-25 A.
