ACS781KLRTR-150U-T Description

Short technical summary and product information.

The Allegro ACS781KLRTR-150U-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 100 A, offering a precise and reliable solution for current measurement applications.

 

This sensor IC operates within a voltage range of 3V to 3.6V and provides a sensitivity of 8.8mV/A with an accuracy of ±0.8%. The device features a fast response time of 3.6µs and operates across a wide temperature range of -40°C to 125°C. Its Hall sensor technology incorporates common-mode field rejection for optimized performance in the presence of interfering magnetic fields.

 

The ACS781KLRTR-150U-T is housed in a compact, low-profile 7-PowerSMD Module package, suitable for surface mounting. This package has a very small footprint, making it ideal for space-constrained designs. The sensor outputs a voltage that varies linearly with the primary current, enabling bidirectional AC or DC current measurement.

 

This device is classified as NOT FOR NEW DESIGN, indicating it is restricted to existing customer applications. For new designs, Allegro recommends the ACS37220.
