HAL® 7xy

Dual Hall-Effect Sensors with two Independent Outputs

Short Description

Note: The HAL 7xy sensor family is not recommended for new designs.

HAL 7xy is a family of monolithic integrated Hall-effect sensors manufactured in CMOS technology with two independent Hall plates S1 and S2. Both devices have two open-drain outputs.
The sensor HAL 730 is particularly featuring a count and a direction output. The count output operates like a single latched Hall switch according to the magnetic field present at Hall plate S1. The direction output indicates the direction of a linear or rotating movement of magnetic objects.
In combination with an active target providing a sequence of alternating magnetic north and south poles, the sensors generate the signals required to control position, speed, and direction of the target movement.
The HAL 7xy sensors include temperature compensation and active offset compensation. These features provide excellent stability and matching of the switching points in the presence of mechanical stress over the whole temperature and supply voltage rang.
The HAL 7xy family is designed for automotive and industrial applications and operate with supply voltages from 3 .8 V to 24 V in the junction temperature range from −40 °C up to 170 °C. The sensors are available in the SMD package SOT89B.
