ATK-I 5/20/30

Current Sensor

Overview

The ATK-I 5/20/30 provides economical and precise solutions for AC or DC

current sensing in industrial, automotive, commercial, and communications

systems. The device package allows for easy implementation by the customer.

Typical applications include motor control, load detection and management,

switched-mode power supplies, and over-current fault protection.

Features

To the device to

be measure 2

(VIOUT(Q)). The output of the sensor when the primary current is zero. For a

unipolar supply voltage, it nominally remains at VCC ⁄ 2. Thus, VCC = 5 V

translates into VIOUT(Q) = 2.5 V. Variation in VIOUT(Q) can be attributed to the

resolution of the Allegro linear IC quiescent voltage trim and thermal drift.

For No current output value is 2.5V

Note: Always connect the measuring device to the green connector. The green

connector should be in series with supply line.
