ACS754xCB-130 is a automotive grade current sensor from Allegro company. The sensor uses single +5 V supply, has 3 kVRMS isolation voltage, 35 kHz bandwidth, ultra-low power loss and high reliability.
The ACS754xCB‑130 is a Hall‑effect current sensor from Allegro MicroSystems that provides a low‑offset, linear voltage output proportional to primary current up to ±130 A. The device integrates a precision Hall IC, a copper conduction path, and isolation between the sensed current path and sensor pins, allowing use without external opto‑isolators.
The datasheet includes electrical characteristics, accuracy definitions, dynamic response parameters, mechanical dimensions, and compliance with safety standards such as UL‑94V‑0 and IEC 60950‑1. It also lists package options (CB‑PSF, CB‑PSS, CB‑PFF) and ordering part numbers.
