Datasheet
AS5134
360 Step Programmable High Speed Magnetic Rotary Encoder
1 General Description
The AS5134 is a contactless magnetic rotary encoder for accurate
angular measurement over a full turn of 360o. 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 absolute angle measurement
provides instant indication of the magnet’s angular position with a
resolution of 8.5 bit = 360 positions per revolution. This digital data is
available as a serial bit stream and as a PWM signal. In addition to
the angle information, the strength of the magnetic field is also
available as a 6-bit code.
Data transmission can be configured for 1-wire (PWM), 2-wires
(DCLK, DIO) or 3-wires (DCLK, DIO, CS).
A software programmable (OTP) zero position simplifies assembly
as the zero position of the magnet does not need to be mechanically
aligned.
?? Two digital 360 step (8.5 bit) absolute outputs: Serial interface
and Pulse width modulated (PWM) output
?? User programmable zero position and sensitivity
?? High speed: up to 76875 rpm
?? Direct measurement of magnetic field strength allows exact
determination of vertical magnet distance
?? Incremental Outputs ABI Quadrature: 90 ppr, step direction:
180ppr, fixed pulse width 360ppr
?? BLDC Outputs UVW, selectable for 1,2,3,4,5,6 pole pairs
?? Daisy-Chain mode for cascading of multiple sensors
?? 9-bit multi turn counter
?? Low power mode with fast startup
?? Wide magnetic field input range: 20- 80 mT
?? Wide temperature range: -40oC to +140oC
?? Fully automotive qualified to AEC-Q100
A Power Down Mode together with fast startup and measurement
cycles allows a very low average power consumption.
?? Small Pb-free
package: SSOP 20
2 Key Features
?? 360o contactless angular position encoding
3 Applications
The AS5134 is suitable for contactless rotary position sensing, rotary
switches (human machine interface), AC/DC motor position control
and Brushless DC motor position control.
