SS543AT Description

Short technical summary and product information.

The Honeywell SS543AT is a solid-state magnetic sensor designed as a unipolar Hall Effect switch. It features an open collector output type and is specified for operation with a supply voltage ranging from 3.8V to 30V.

 

This sensor is temperature compensated, ensuring reliable performance across its operating temperature range of -40°C to 150°C. The sensing range is defined by a 18mT trip point and a 7.5mT release point. The device requires a supply current of up to 10mA and can provide an output current of up to 50mA.

 

Packaged in a SOT-89B (TO-243AA, Variant) surface-mount package, the SS543AT is suitable for various electronic designs. It is polarized for South Pole sensing.

 

Environmental compliance includes RoHS3 compliance, MSL 1, and REACH unaffected status. The SS543AT is suitable for applications requiring precise magnetic field detection and switching.
