The Silicon Labs SI7201-B-87-IVR is a high-sensitivity Hall effect magnetic sensor switch. It combines a chopper-stabilized Hall element with digital signal processing for precise compensation of temperature and offset drift. This device offers omnipolar operation, meaning it responds to both north and south magnetic poles.
Key electrical specifications include a wide operating voltage range of 1.71V to 5.5V and a very low typical current consumption of 400 nA. The sensing range is ±3.7mT for trip and ±1.4mT for release. It operates across a temperature range of -40°C to 125°C.
This Hall effect switch is housed in an industry-standard 3-pin SOT-23 package, suitable for surface mounting. Its features include tamper detection and digital signal processing for temperature and offset drift compensation. The SI7201 family is designed for applications requiring reliable magnetic position sensing, such as consumer electronics, security systems, and mechanical device position sensing.
Applications include position sensing for HVAC knobs, door locks, windows, BLDC motor control, camera image stabilization, fluid level sensing, and general-purpose mechanical position sensing.
