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). On-chip EEPROM supports flexible end-of-line programming of calibration parameters with up to 100 read/write cycles. Ideal for automotive applications like electronic power steering (EPS), rotary PRNDLs, and throttle systems, the A1339 is designed for safety-critical applications.
