Product Description
Product Overview
The A1339 is a 360 angle sensor IC utilizing Circular Vertical Hall (CVH) technology to provide contactless, high-resolution angular position information. Its system-on-chip (SoC) architecture integrates a CVH front end, digital signal processing, and motor commutation (UVW) or encoder outputs (A, B, I). With on-chip EEPROM for flexible calibration parameter programming, the A1339 is ideal for automotive applications such as electronic power steering (EPS), rotary PRNDLs, and throttle systems, supporting safety-critical integrations.
