Honeywell Sensing & Control Nanopower Magnetoresistive Sensor ICs

Honeywell Nanopower Series Magnetoresistive (MR) Sensor ICs are ultra-sensitive devices designed to accommodate a vast array 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. This simplifies installation and potentially reduces system cost.

These sensor ICs utilize a very low average current consumption and a push-pull output that does not require a pull-up resistor. The Nanopower series promotes energy efficiency by operating from a supply voltage as low as 1.65V.

These Magnetoresistive Sensor ICs, Nanopower Series, are supplied in the sub-miniature SOT-23 surface mount package on tape and reel (3000 units per reel), for use in automated pick-and-place component installation.
