The Allegro MicroSystems ACS781LLRTR-100B-T is a fully integrated, automotive-grade linear Hall-effect-based current sensor IC. It is designed to accurately measure both AC and DC currents up to 100A. The device features a low-profile, core-less package with a very small footprint, making it suitable for space-constrained applications. Its Hall sensor technology incorporates common-mode field rejection for optimized performance in the presence of interfering magnetic fields.
The ACS781LLRTR-100B-T provides a ratiometric voltage output that varies linearly with the primary current. Key electrical specifications include a sensitivity of 13.2mV/A, an accuracy of ±1.5%, and linearity of ±1%. It operates within a voltage range of 3V to 3.6V and has a frequency response up to 120kHz. The sensor has a response time of 3.6µs and operates across a wide temperature range of -40°C to 150°C.
This sensor IC is designed for surface mount applications and comes in a 7-PowerSMD Module package. It is suitable for bidirectional current measurements. The device benefits from Allegro's proprietary integrated shield technology, offering high-level immunity to current conductor dV/dt and stray electric fields, resulting in low-output voltage ripple and low-offset drift in high-side, high-voltage applications.
Note: This part has been determined to be NOT FOR NEW DESIGN. Sale is restricted to existing customer applications, and it is not recommended for new design applications due to probable obsolescence.
