General Description

The Allegro™ A1367 programmable linear Hall-effect current sensor IC has been designed to achieve high accuracy and resolution without compromising bandwidth.

This goal is achieved through new proprietary linearly interpolated temperature compensation technology that is programmed at the Allegro factory and provides sensitivity and offset that are virtually flat across the full operating temperature range.

Temperature compensation is performed in the digital domain with integrated EEPROM technology while maintaining a 240 kHz bandwidth analog signal path, making this device ideal for HEV inverter, DC-to-DC converter, and electric power steering (EPS) applications.

Overview

A1367 Low-Noise, High-Precision, Programmable Linear Hall-Effect Sensor IC with Regulated Supply, Advanced Temperature Compensation, and High-Bandwidth (240 kHz) Analog.

Key Features

  • 240 kHz nominal bandwidth achieved via proprietary packaging and chopper stabilization techniques.
  • On-board supply regulator with reverse-battery protection.
  • Proprietary segmented linear temperature compensation (TC) technology provides a typical accuracy of 1% over the full operating temperature range.
  • Customer-programmable, high-resolution offset and sensitivity trim.
  • Factory-programmed sensitivity and quiescent output voltage TC with extremely sta.
