HAL 15xy

Hall-Effect Switches with Open-Drain Output (3-wire) in SOT23 Package

Release Note: Revision bars indicate significant changes to the previous edition.

1. Introduction

The HAL 15xy Hall-switch family members produced in CMOS technology as 3-wire

device with open-drain output transistor include a temperature-compensated Hall plate

with active offset compensation, a comparator, and an output stage.

The comparator compares the actual magnetic flux through the Hall plate (Hall voltage)

with the fixed reference values (switching points). Accordingly, the output transistor is

switched on or off.

The active offset compensation leads to constant magnetic characteristics over supply

voltage and temperature range. In addition, the magnetic parameters are robust against

mechanical stress effects.

The sensors are designed for industrial and automotive applications and operate with

supply voltages from 2.7 V to 24 V in the junction temperature range from 40 C up to

170 C.

HAL 15xy is available in a JEDEC TO236-compliant SMD-package 3-lead SOT23.
