FEATURES
General Description
The AS5045B is a contact less magnetic position sensor for accurate angular measurement over a full turn of 360 degrees. It is a system-on-chip, combining integrated Hall elements, analog front end and digital signal processing in a single device. To measure the angle, only a simple two-pole magnet, rotating over the center of the chip, is required. The magnet can be placed above or below the IC.
Key Features
Contact less high resolution rotary position sensor over a full turn of 360 degrees
Two digital 12-bit absolute outputs:
- Serial interface
- Pulse width modulated (PWM) output
Quadrature A/B/I output 12-bit
User programmable zero position
Failure detection mode for magnet placement, monitoring, and loss of power supply
Red-Yellow-Green indicators display placement of magnet in Z axis
Serial read-out of multiple interconnected AS5045B devices using Daisy Chain mode
Tolerant to magnet misalignment and gap variations
Wide temperature range: - 40ºC to +125ºC
Small Pb-free package: SSOP 16 (5.3mm x 6.2mm)
Applications
The device is ideal for industrial applications like automatic or elevator doors, robotics, motor control and optical encoder replacement.
