The A1333 is a 360° angle sensor IC that provides contactless, low latency, high-resolution angular position information based on magnetic Circular Vertical Hall (CVH) technology. It has a system-onchip (SoC) architecture that includes: a CVH front end, digital signal processing, and motor commutation (UVW) or encoder outputs (A, B, I). It also includes on-chip EEPROM technology, capable of supporting up to 100 read/write cycles, for flexible end-of-line programming of calibration parameters.
The A1333 is ideal for automotive applications requiring 0° to 360° angle measurements, such as electronic power steering (EPS), rotary PRNDLs, and throttle systems.
The A1333 supports customer integration into safety-critical applications.
The A1333 is available in a dual-die 24-pin eTSSOP and a single-die 14-pin TSSOP package. The packages are lead (Pb) free with 100% matte-tin leadframe plating.
Allegro’s single and dual die A1333 devices were designed in accordance with ISO26262:2011 requirements for hardware product development for use in safety-critical applications(pending assessment). The single die version was designed to meet ASIL B requirements and the dual die was designed to meet ASIL D requirements when integrated and used in conjunction with the appropriate system level control, in the manner proscribed in the A1333 Safety Manual.
