The ACS780xLR is a high-precision, coreless Hall-effect current sensor IC with a 200 μΩ internal conductor, designed for AC and DC current measurement up to 100 A in automotive applications. It operates from a 4.5 to 5.5 V single supply, has a 120 kHz bandwidth, and a 3.6 μs output rise time. The device is packaged in a 7-pin PSOF (LR suffix) with a thickness of 1.5 mm and is AEC-Q100 qualified. The ACS780LLRTR-100B-T variant senses bidirectional currents from ±50 A to ±100 A with a sensitivity of 20 mV/A. It features integrated shielding for high dV/dt immunity, factory-trimmed accuracy, and operates from −40 °C to 150 °C. The part is not for new design and has been superseded by the ACS37220.
The ACS780 offers accurate and efficient current sensing for automotive applications, featuring a coreless design, 200µΩ conductor for low power loss, and integrated protection against common-mode field interference.
