ACS764 - Hall-Effect Based Current Sensor

Description

The Allegro™ ACS764 fully integrated Hall-effect current sensor IC is designed for applications that require digital current sensing and reporting through an I2C™ bus.

Features

  • Fully integrated current sensor IC in a compact QSOP package eliminates the need for shunt resistors.
  • Hall effect sensing technology eliminates the error associated with shunt resistor variation due to temperature.
  • High accuracy: typical error < 2% over operating temperature range.
  • Fast response digital fault output with programmable level through I2C bus interface.
  • Digital output through I2C interface with 9-bit A-to-D conversion for high resolution.
