描述 Description

The Broadcom AEAT-8800-Q24 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 complex analog and digital signal processing?within a single device.?A simple two-pole magnet generates the necessary magnetic?field by rotating it in perpendicular, placed in alignment to the?center of the device.
The Broadcom AEAT-8800-Q24 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 one-time programmable resolution of 10, 12, 14?or 16 bits.?When selected, its positioning data is then represented in its?digital form to be assessed through a standard SSI 3 wire?communication protocol. Where desired, users may also?choose to receive its absolute angle position in PWM-encoded?output signals.
The incremental positions are indicated on ABI and UVW?signals with user configurable CPR 32, 64, 128, 256, 512, 1024,?2048, and 4096 of ABI signals and pole pairs from 1 to 8 (2 to?16 poles) for UVW commutation signals. An internal voltage?regulator allows the AEAT-8800-Q24 to operate at either 3.3V or?5V supplies.
