ACS712ELCTR-30A-T

Product Summary

ACS712ELCTR-30A-T 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 overcurrent
fault protection.
The ACS712ELCTR-30A-T device consists of a precise, low-offset,
linear Hall sensor circuit with a copper conduction path located near
the surface of the die. Applied current flowing through this copper
conduction path generates a magnetic field which is sensed
by the integrated Hall IC and converted into a proportional
voltage.
ACS712ELCTR-30A-T is provided in a small, surface mount SOIC8 package.
The leadframe is plated with 100% matte tin, which is compatible
with standard lead (Pb) free printed circuit board assembly processes.
Internally, the device is Pb-free, except for flip-chip high-temperature
Pb-based solder balls, currently exempt from RoHS. The device is
fully calibrated prior to shipment from the factory.
