The SS443A is a temperature compensated digital hall effect sensor IC in 3 pin TO-92 package. This small, versatile digital hall effect device is operated by magnetic field from permanent magnet or an electromagnet. It is designed to respond to alternating north and south poles or to south pole only. Band gap regulation provides stable operation over 3.8VDC to 30VDC supply voltage range. The SS443A is capable of continuous 20mA sinking output and may be cycled as high as 50mA maximum. Its 3.8V capability allows for use in many potential low voltage applications. The digital, open collector sinking type output is easily interfaced with wide variety of electronic circuits.
- Unipolar magnetics, medium gauss operating characteristics
- Straight leads, 14.99mm long and 1.30mm spacing
- Quad hall IC design minimizes mechanical stress effects
- Temperature compensated magnetics helps provide stable operation over a wide temperature range
- Automated component placement and potentially reduces installation costs
- Broad supply voltage capability from 3.8VDC to 30VDC for application flexibility
- Digital, open collector sink output for easy interfacing with variety of common electronic circuits
- Operating temperature range from -40°C to 150°C (-40°F to 302°F)
Applications
Sensing & Instrumentation, Medical, Industrial, Robotics, Motor Drive & Control

Easy to use! No more hand cranking.
If you like the ease of an electric can opener, but don’t have room to store it or don’t want to drag it out when you need to use it, this is for you. I like a handheld can opener, but would get so frustrated trying to use it and turn the handle. This can opener is amazing and so easy to use. Just attach to can and push a button. It starts turning on its own and when it is done it stops. You lift it up and the lid comes off cleanly. It is rechargeable so need to worry about batteries. It tucks away in a drawer nicely. I bought my mom one too. She has arthritis in her hands so thought this would be perfect for her.

Smooth edges better than twisting
Works a lot better than the crank style and the counter top electric and you can use the lid to reseal the can if you don't use the whole thing.

Worked for only 4 months. Now produces metal shards. Dangerous
Pros: Can be used with one hand. I bought this to have after surgery that left me without use of one arm for a few months. The light blinks when you need to charge it. Only needs a 2-3 min charge for enough juice to open a can.
Cons: IT QUIT CUTTING CORRECTLY AFTER 4 MONTHS. I now have to use both hands to hold it in place to get it to latch on to the can. It also requires a few rotations around the top to cut through the seal, resulting in METAL SHARDS! The metal shards are super sharp and almost invisible. I stabbed myself with one enough to draw blood. This is dangerous as the metal could fall into the food when pouring from the can.
