HAL740SF-K Description

Short technical summary and product information.

The Micronas HAL740SF-K is a dual, unipolar Hall effect switch designed for various sensing applications. It utilizes Hall Effect technology to detect magnetic fields, offering both North and South pole sensing capabilities.

 

This device features an open drain output and operates over a broad voltage range of 3.8V to 24V, with a typical current consumption of 9mA. The operating temperature range is extensive, spanning from -40°C to 140°C (TA), making it suitable for demanding environments. Its sensing range is specified as -16mT Trip and -3.5mT Release for one threshold, and 16mT Trip and 3.5mT Release for the other.

 

Packaged in a TO-243AA, Variant (SOT-89B-2) format, the HAL740SF-K is designed for surface mount applications. It is RoHS3 compliant and has a Moisture Sensitivity Level (MSL) of 1 Unlimited, indicating its robustness against moisture ingress. The device is also noted as REACH Unaffected.

 

Key features include temperature compensation, ensuring stable performance across its operating temperature range. The dual function allows for versatile magnetic switching applications where precise detection of magnetic poles is required.
