Allegro MicroSystems, LLC Corporation introduces the first digital current sensor IC targeted at server, telephony, and power overseeing current sensor Ed applications within the professional, consumer and laptop or computer markets. Allegro’s ACS764 fully incorporated Hall-effect current sensor Ed is designed for applications that require digital current sensing and reporting using an I²￠ bus.

Allegro factory programming of the offset and also gain, including the heat coefficients, stabilizes the balance out and gain within the operating temperature array. This programming drastically reduces the device overall error, typically under 2% over the operating heat range. The incorporated low resistance conductor eradicates the requirement for external shunt resistors as well as, by employing Hall-effect sensing technologies, eliminates the error associated with changing sense level of resistance due to temperature. The product allows 16 distinctive I²C bus addresses, selectable via external pins. The particular ACS764 sensor IC full scale 16 A new and 32 A unidirectional sensing are regular options. The device also incorporates a digital over-current wrong doing output and inner averaging filter, as both versions are user configurable through the I2C bus. A digital synchronization insight pin also provides to be able to obtain multiple sensor readings with the same period stamp.

The ACS764XLFTR-T is given in a compact 24-pin QSOP deal (suffix LF). The leadframe is coated with 100% matte metal, which is compatible with common lead (Pb) free printed circuit board assembly processes. Inside the camera, the device is Pb-free, apart from flip-chip high-temperature Pb-based solder balls, currently free from RoHS. It costs $1.60 in quantities of 1,000.
