General Description

The A1454 linear Hall-effect sensor IC provides a 12-bit digital output word that is proportional to the strength of the magnetic field that is present.

Its quiescent output value is at mid-scale, and it comes in two different factory-programmed sensitivity ranges: 2 LSB/G and 4 LSB/G.

The sensitivity temperature coefficient is also factory-programmed to support either neodymium or ferrite magnets.

Overview

A1454 3 V Hall-Effect Linear Sensor with I2C Output.

Key Features

  • 1 mm thin 8-pin TSSOP package.
  • Two factory-programmed sensitivity options:.
  • 2 LSB/G (for fields up to ±1000 G).
  • 4 LSB/G (±500 G).
  • Temperature-stable sensitivity for NdFeB and ferrite magnets.
  • I2C interface for easy integration, with support for up to 127 unique addresses.
  • EEPROM stores factory-programmed settings and up to 26 bits of user information (programmable through the I2C interface).
  • Micropower sleep mode through I2.
