SI7201-B-32-IVR Description

Short technical summary and product information.

The Silicon Labs SI7201-B-32-IVR is a Hall effect magnetic switch designed for various position sensing applications. It features an omnipolar operation, meaning it can detect both north and south magnetic poles. The device operates within a wide power supply voltage range of 1.71V to 5.5V and has a typical current consumption of 1.2µA.

 

Key electrical characteristics include an open drain output type and a sensitivity range of ±7mT Trip and ±4.1mT Release. The operating temperature range is from -40°C to 125°C. The sensor integrates digital signal processing for compensation of temperature and offset drift, offering a sensitivity drift of less than ±3% over temperature.

 

This component is supplied in a surface-mount SOT-23-3 package, making it suitable for compact designs. Its features make it applicable for replacing reed switches and for general-purpose mechanical position sensing in consumer electronics, security systems, and automotive applications.
