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.
