A19420 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.
A19420 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 a
- 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 supporting speed and ASIL error reporting
- EEPROM enables traceability throughout product life cycle
