![Nanopower Series anisotropic magnetoresistive (AMR) sensor IC, omnipolar, high sensitivity (7 G typ.), SOT-23, 3000 units/tape and 178 mm [7 in] reel - SM351LT - Honeywell Sensing & IoT](https://partimages.globalspec.com/06/0756/4600756_medium.png)
Honeywell’s Nanopower Series anisotropic magnetoresistive (AMR) sensor ICs are ultra-sensitive devices designed to accommodate a wide range of applications with large air gaps, small magnetic fields and low power requirements. The sensor ICs respond to either a North or South pole applied in a direction parallel to the sensor. They do not require the magnet polarity to be identified, simplifying installation and potentially reducing system cost. These sensor ICs use a very low average current consumption and a push-pull output which does not require a pull-up resistor. The sensor ICs can operate from a supply voltage as low as 1.65 V, promoting energy efficiency.
SM351LT: For applications requiring ultra high magnetic sensitivity (7 Gauss typical operate, 11 Gauss maximum operate) and a very low current draw (360 nA typical).
The Nanopower Series Magnetoresistive Sensor ICs are designed for a wide range of applications due to their ultra-sensitive nature. They can be used in applications with large air gaps, small magnetic fields and where there is a low power requirement. Instillation is simplified as they do not require the magnetic polarity to be identified and they will respond to either the north or south pole applied in a direction parallel to the sensor which potentially could help reduce system costs. The sensors are very efficient and can be operated on a supply voltage as low as 1.65 V with a very low average current consumption and a push-pull output which does not require a pull-up resistor, again reducing costs.
