Description
The H1812T800R-00 is a micropower Omnipolar Hall effect switch IC, designed for portable and battery-powered equipment such as portable PCs and mobile phones. This high sensitivity switch IC has an open-drain output and can operate over supply ranges of 1.6V to 3.6V. The AH1812 uses a hibernating clocking system that minimizes power consumption while providing excellent temperature stability and immunity to stress.

Comparison
Advantages- The AH1812 is designed for portable and battery-powered equipment
- Micropower operation with a low average supply current conserves battery life
- The chopper-stabilized design provides superior temperature stability and immunity to stress, and minimizes switch-point drift
- The Hall effect switch is an omnidirectional sensor that can be triggered by the presence of either a North or South pole
Disadvantages- The H1812T800R-00 is only suitable for use with devices operating within a supply voltage range of 1.6V to 3.6V
- This device may not be suitable for high-frequency applications due to its low RF noise immunity
