ACS730KLCTR-20AB-T Description

Short technical summary and product information.

The Allegro MicroSystems ACS730KLCTR-20AB-T is an integrated Hall Effect current sensor IC designed for AC or DC current sensing in industrial, commercial, and communications systems. It offers a 20A current rating with a sensitivity of 100mV/A and a bandwidth of 1MHz.

 

This device features a precise, low-offset linear Hall sensor circuit with a low internal resistance copper conduction path (typically 1.2 mΩ) for minimal power loss. The output is ratiometric and proportional to the applied current, with bidirectional polarization. Accuracy is rated at ±3% and linearity at ±0.75%.

 

The ACS730KLCTR-20AB-T is provided in a small, low-profile 8-SOIC surface-mount package, allowing for easy implementation. The terminals of the conductive path are electrically isolated from the sensor leads, enabling high-side current sensing without complex isolation techniques. The operating temperature range is -40°C to 125°C.

 

Note: This device is classified as NOT FOR NEW DESIGN and is restricted to existing customer applications due to probable obsolescence.
