Introduction

The HAL880 is a new member of the Micronas family of programmable linear Hall sensors. The HAL880 complements the existing Hall-effect sensor family HAL8xy to the lower end. It is designed to fulfill the requirements of today’s state-of-the-art applications for linear and angular measurements that require programmability to compensate system tolerances.

Features

– programmable linear Hall effect sensor with ratiometric output and digital signal processing

– 12-bit analog output

– multiple programmable magnetic characteristics in a non-volatile memory (EEPROM) with redundancy and lock function

– open-circuit (ground and supply line break detection) with 10 kΩ pull-up and pull-down resistor, overvoltage and undervoltage detection

– for programming an individual sensor within several sensors in parallel to the same supply voltage, a selection can be done via the output pin

– temperature characteristics are programmable for matching common magnetic materials

– programmable clamping function

– programming through a modulation of the supply voltage

– operates from −40 °C up to 140 °C junction temperature

– operates from 4.5 V up to 5.5 V supply voltage in specification and functions up to 8.5 V

– operates with static magnetic fields and dynamic magnetic fields up to 1 kHz

– overvoltage and reverse-voltage protection at all pins

– magnetic characteristics extremely robust against mechanical stress

– short-circuit protected push-pull output

– EMC and ESD optimized design

Major Applications

Due to the sensor’s versatile programming characteristics and low temperature drifts, the HAL880 is the optimal system solution for applications such as:

– contactless potentiometer,

– rotary position measurement,

– linear movement,

– current measurements.
