Honeywell Sensing & Control Nanopower 磁敏传感器 IC
Honeywell Nanopower Series Magnetoresistive (MR) 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. The Nanopower Series is available in two magnetic sensitivities to accommodate a variety of application needs: SM351LT: For applications requiring ultra high magnetic sensitivity (7 G typical operate, 11 G maximum operate) and a very low current draw (360 nA typical). SM353LT: For applications requiring very high magnetic sensitivity (14 G typical operate, 20 G maximum operate) and a very low current draw (310 nA typical). These Magnetoresistive Sensor ICs, Nanopower Series, are supplied in the subminiature SOT-23 surface mount package on tape and reel (3000 units per reel), for use in automated pick-and-place component installation.These sensor ICs utilize a very low average current consumption and a push-pull output that does not require a pull-up resistor.
