Features:
SM353LT all-pole magnetoresistive 310nA Hall sensor with a magnetic sensitivity of 14 to 20G from Honeywell
Nanopower series all-pole magnetoresistive sensors with integrated circuits for all-pole position sensors. SOT-23. The typical value is 7 G, and the value is 11 G (SM351LT); The typical value is 14 G and the value is 20 G (SM353LT); The typical current is 360 nA (SM351LT) and 310 nA (SM353LT).
Magnetosensitive resistor sensor IC (Integrated Circuit)
Honeywell Nanopower series magnemistor (MR) sensor ics are highly sensitive devices, widely suitable for applications with large air gaps, small magnetic fields and low power requirements.
The sensor IC should be installed parallel to the south or North Pole in the direction of the sensor, without the need for additional identification of magnetic poles, which simplifies the installation and potentially saves costs.The average current consumption of these sensor ics is extremely low. The output is a push-pull output without a pull-up resistor, and the operating voltage is as low as 1.65V, which can significantly improve energy efficiency.
These Nanopower series magnemistor sensor ics adopt the ultra-small SOT-23 surface mount package. The packaging is in the form of tape and reel, with 3,000 pieces per reel, which is suitable for the installation of components using automated sorting and placement.
