ACS781LLRTR-050U-T Description

Short technical summary and product information.

The Allegro ACS781LLRTR-050U-T is a fully integrated, automotive-grade linear Hall-effect based current sensor IC. It is designed to sense AC and DC currents up to 50A with high precision and accuracy.

 

The device operates within a voltage range of 3V to 3.6V and offers a sensitivity of 39.6mV/A with an accuracy of ±1.5% and linearity of ±1%. It has a fast response time of 3.6µs and a frequency response up to 120kHz.

 

Packaged in a 7-PowerSMD Module, this sensor IC is suitable for surface mount applications. It incorporates common-mode field rejection for optimized performance in the presence of interfering magnetic fields. The ACS781xLR series is noted as 'Not for New Design' and is recommended for existing customer transitions, with ACS37220 suggested for new applications.

 

This sensor is ideal for applications requiring precise current monitoring in automotive and industrial systems. Its low-profile, small footprint package makes it suitable for space-constrained designs.
