ACS780LLRTR-100U-T Description

Short technical summary and product information.

The Allegro ACS780LLRTR-100U-T is a fully integrated, automotive-grade Hall Effect current sensor IC capable of measuring AC and DC currents up to 100A. It utilizes a precision, low-offset linear Hall circuit with an integrated copper conduction path. This design allows for accurate current sensing with a sensitivity of 40mV/A and an accuracy of ±1.5%.

 

The device operates within a voltage range of 4.5V to 5.5V and has an operating temperature range of -40°C to 150°C. Its output is ratiometric and provides a voltage signal proportional to the primary current. The sensor has a response time of 3.6µs and supports frequencies up to 120kHz.

 

Packaged in a 7-PowerSMD Module (7-PSOF), the ACS780LLRTR-100U-T is designed for surface mounting. It is a single-channel sensor with a unidirectional polarization for DC current measurement. The sensor incorporates common-mode field rejection and proprietary integrated shield technology for enhanced performance in noisy environments.

 

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