AEAT-9922 Datasheet | Broadcom

Description The Broad® AEAT-9922 is an angular magnetic rotary sensor that provides accurate angular measurement over a full 360 degrees of rotation. It is a sophisticated system that uses integrated Hall sensor elements with plex analog and digital signal processing within a single device. A simple two-pole magnet generates the necessary magnetic field by rotating it in perpendicular. Wide magnetic field sensor configurations allow On-Axis (end of shaft) or Off-Axis (side of shaft) modes in application. The Broad AEAT-9922 is a versatile solution capable of supporting a broad range of applications with its robust architecture to measure and deliver both absolute and incremental signals. The absolute angle measurement provides an instant indication of the magnet’s angular position with a selectable and reprogrammable resolution from 10 bits to 18 bits. When selected, its positioning data is then represented in its digital form to be assessed through a standard SSI (parity) and SPI (with CRC and Parity option) munication protocol. Where desired, users may also choose to receive its absolute angle position in PWM-encoded output signals with initialization and error bits option. The incremental positions are indicated on ABI and UVW signals with wide user configurable resolution from 1CPR and up to 10,000 CPR of ABI signals and pole pairs from 1 to 32 pole pairs (2 to 64 poles) for UVW mutation signals.
