PACKAGES 24-pin eTSSOP (Suffix LP) 14-pin TSSOP (Suffix LE) DESCRIPTION The AAS33001 is a 360° angle sensor IC that provides contactless high-resolution angular position information based on magnetic circular vertical Hall (CVH) technology.
It has a system-on-chip (SoC) architecture that includes: a CVH front end, digital signal processing to calculate the angular position information, and multiple output formats: serial protocol (SPI), pulse-width modulation (PWM), and either 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 programming of calibration parameters.
TheAAS33001 is ideal for automotive a...
