Allegro MicroSystems Intros ACS754/5 Current Sensors

November 21, 2004 by Jeff Shepard

Allegro MicroSystems Inc. (Worcester, MA), a supplier of mixed-signal power semiconductors and hall-effect sensors, announced its new ACS754/5 family of current sensors, which extends the existing ACS752 family. The devices provide a smaller, lower-cost alternative to toroid-based sensors, and offer economical and precise current sensing in industrial, consumer, communications and automotive systems, with end applications to include automotive EPS, motor control, battery management, UPS and emergency lighting, power distribution, white goods and electric vehicles.

The ACS754 devices are bi-directional sensors, while the ACS755 versions offer single-direction sensing with approximately twice the resolution of the bi-directional ACS754s. The devices provide 3 kV isolation and single-voltage supply operation while placing only 100 µΩ of resistance in the current path; 50 A, 100 A, 130 A, 150 A and 200 A versions are available in both industrial and automotive temperature ranges. The lead-free, PC-mountable package is only 14 mm x 22 mm x 7 mm, and integrates the current path.

The new ACS754 current sensors are priced at $7.10 in quantities up to 1,000, with a lead time to market of 8 to 10 weeks.
