General Description
The A19420 is an optimized Hall-effect integrated circuit (IC) that measures the speed of rotating targets.
This sensor IC can be used to directly measure ring magnets or be back-biased with a magnet to measure ferrous targets.
Key Features
- Differential Hall-effect sensor measures ring magnets and ferrous targets with inherent stray field immunity.
- SolidSpeed Digital Architecture supports advanced algorithms, maintaining pitch and duty cycle accuracy during dynamic air gap disturbances.
- Integrated solution includes a capacitor in a single overmolded package.
- ISO 26262:2011 ASIL B with integrated diagnostics and certified safety design process.
- Two-wire current source output protocol sup.
