Global electronic components distributor Digi-Key Corporation, the industry leader in electronic component selection, availability and delivery, today announced stock of Honeywell’s new Nanopower line of magnetoresistive sensor ICs.
These devices are designed to accommodate a wide range of applications with large air gaps, small magnetic fields, and lower power requirements. They respond to either a North or South pole applied in a direction parallel to the sensor and do not require a pull-up resistor.
Honeywell’s Nanopower ICs use a very low average current consumption and a push-pull output, which does not require a pull-up resistor, operating from a supply voltage as low as 1.65 V, promoting energy efficiency. The series is available in two magnetic sensitivities to accommodate a variety of application needs: SM351LT for applications requiring ultra high magnetic sensitivity and a very low current draw (360 nA typical); and SM353LT for applications requiring very high magnetic sensitivity and a very low current draw (310 nA typical). The devices are supplied in the sub-miniature SOT-23 surface mount package on tape and reel for use in automated pick-and-place component installation.
These ICs reduce system cost and provide a durable alternative to reed switches in low-power battery applications, including industrial, medical, white goods, and consumer electronics.
