SM353LT Honeywell, Omnipolar Magnetoresistive Sensor, 3-Pin SOT-23

Honeywell Nanopower Series

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.
