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. instilllation 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. Potential Applications Industrial: Mobile equipment (i.e., handheld computing equipment, scanners) Water, electric and gas utility meters Building access control; reed switch replacement for battery-operated security systems Industrial smoke detectors Medical: Exercise equipment Infusion pumps Drawer position sensing (e.g., medical cabinets) Hospital beds White Goods: Lid, door and drawer position detection Fluid flow Medium-sized Consumer Electronics: Battery-optimization position sensor
