ACS772ECB-250B-PSF-T

Current Sensors Overview

The ACS772ECB-250B-PSF-T is a fully integrated, high-performance Hall effect-based current sensor IC designed for board-mount applications. It provides galvanic isolation between the current-carrying conductors and the signal output circuitry. The device features a 250A current rating with an 8mV/A sensitivity and supports bidirectional measurement of AC and DC currents. Operating within a supply voltage range of 4.5V to 5.5V, it delivers a ratiometric analog voltage output. Key electrical specifications include a 2.5µs response time, linearity of ±0.9%, and a frequency bandwidth from DC to 200kHz. It is housed in a 5-CB package with formed leads.

Current Sensors Procurement Notes

Verify that the specific suffix PSF-T matches the required lead configuration and tape-and-reel packaging format against the official datasheet. Confirm the operating temperature grade and AEC-Q100 automotive qualification status if applicable to the target environment. Ensure the supply voltage range aligns with the system design before procurement.

Current Sensors Selection Notes

Select this component when a 250A current capacity and bidirectional sensing capability are required. The 8mV/A sensitivity and ratiometric output simplify interfacing with standard microcontrollers or ADCs. Consider the 200kHz bandwidth and 2.5µs response time for high-frequency switching applications. Verify thermal management requirements due to the internal copper conductor resistance.

Current Sensors Part Context

This part belongs to the ACS772 series of current sensors from Allegro MicroSystems. The series is characterized by its use of proprietary Hall latches and CMOS signal processing circuitry. The ACS772 family offers various current ratings and package options, providing designers with flexible solutions for high-current monitoring in demanding industrial and automotive environments.

Current Sensors Replacement Considerations

Direct substitutes within the same series include ACS772ECB-250B-PFF-T, which shares identical electrical characteristics but differs in the lead form (PFF vs PSF). Designers must verify mechanical footprint compatibility when swapping between these package variants.
