Honeywell SM351LT Nanopower Omnipolar Hall Effect Sensor - SOT-23-3 Package
The Honeywell SM351LT is a nanopower, omnipolar Hall effect sensor in a compact SOT-23-3 package, designed for ultra-low-power applications. It operates from 1.65V to 5.5V, making it compatible with a wide range of microcontrollers and battery-powered systems, and provides a push-pull output for simplified circuit design.
Features
- Ultra-low nanopower consumption with 360 nA average current
- High sensitivity with 7 Gauss typical, 11 Gauss maximum operating range
- Wide supply voltage range from 1.65 VDC to 5.5 VDC
- Omnipolar sensing activates with either North or South magnetic pole
- Push-pull output eliminates need for external pull-up resistor

The SM351LT is a non-chopper stabilized Hall effect sensor engineered for exceptional power efficiency and reliable magnetic field detection. Its nanopower architecture draws an average current of just 360 nA, making it ideal for battery-critical and energy-harvesting applications where long-term operation is paramount.
Featuring omnipolar operation, the sensor activates in the presence of a sufficiently strong magnetic field of either polarity, simplifying magnet placement and system design. The integrated push-pull output stage provides a clean digital signal, directly compatible with microcontroller GPIO pins without additional components. The device is specified for operation across the industrial temperature range of -40°C to 85°C and is housed in a RoHS-compliant SOT-23-3 surface-mount package.
