INFINEON TLE4997E2XALA1 Hall Effect Sensor, Linear, Ratiometric, 1 mA, SSO, 3 Pins, 4.5 V, 5.5 VThe TLE4997E2 is a Linear Hall Effect Sensor designed specifically to meet the demands of highly accurate rotation and position detection, as well as for current measurement applications. The sensor provides a ratiometric analogue output voltage, which is ideally suited to Analogue to Digital (A D) conversion with the supply voltage as a reference. The IC is produced in BiCMOS technology with high voltage capability and also provides reverse polarity
The TLE4997E2 is a Linear Hall Effect Sensor designed specifically to meet the demands of highly accurate rotation and position detection, as well as for current measurement applications. The sensor provides a ratiometric analogue output voltage, which is ideally suited to Analogue-to-Digital (A/D) conversion with the supply voltage as a reference. The IC is produced in BiCMOS technology with high voltage capability and also provides reverse polarity protection. Digital signal processing using a 16-bit DSP architecture and digital temperature compensation guarantees excellent stability over a long period of time. The minimum overall resolution is 12bits. Some internal stages work with resolutions up to 20bits.The chopped Hall-effect cell and continuous-time A to D conversion provide very low and stable magnetic offset.
- Magnetic flux is measured by a hall effect cell
- Programmable low-pass filter reduces the noise
- Temperature is measured and A to D converted
- Digital processing of output voltage is based on zero field and sensitivity value
- Output voltage range can be clamped by digital limiters
- Final output value is D to A converted
- Output voltage is proportional to the supply voltage (ratiometric DAC)
- On-board-diagnostics (OBD) circuit connects the output to VDD or GND in case of errors
Applications
Sensing & Instrumentation, Automotive, Test & Measurement, Motor Drive & Control

Pee pad tray
Size: Small: 24" x 24"
Love this pad . My little girl loves it too. No messes to cleanup just change the pad and it’s all good…

Protects floors
Size: X-Large: 28" x 34"
I love these pee pad holders. My dog goes near the edge of the pad and the urine gets on my hardwood floors. With these pads the edges of the pee pad holder catches the urine before it gets on the floors. It is very easy to clean the pad holder. I am so thankful it protects my floors!

Works well with the pads. Keeps them from getting bunched up all over the floor.
Size: Small: 24" x 24"
It was a nice idea, but my dogs chewed it up. If you don't have a chewer, then it's really nice.

Saved my sanity
Size: Small: 24" x 24"
I thought I knew everything about cats, but when my 14 year old cat stopped using the litter box, I could not fix it. I did persuade her to start using puppy pads but the problem was she would pee toward the edge and it always got on the floor. Or, defying everything I know about reality, she would find a way to pee UNDER the puppy pad.
I asked ChatGPT for advice and it recommended these. They fixed the problem by 80% and I'll take it! These mats help a ton. She still gets some pee on the floor, but it's not the huge problem it used to be. The edge on the mat keeps it contained. And enzymatic cleaner works its magic on the floor.
The clips that go on the edges are kinda fragile, but that's why they give you extras.
