Dual Die, Hall-Effect Angle Sensors Address Motor Position Applications
Allegro MicroSystems

Primed for safety-critical automotive applications, the dual-die A1331 and A1334 angle sensor ICs are based on vertical Hall-effect technology. They are offered in TSSOP-24 packages that contain two individually sawn, electrically isolated silicon ICs. Onboard digital signal processing functions and EEPROM for factory and customer programmability makes the sensors suitable for on-axis/end-of-shaft angle sensing applications.
