360 Step (8.5 bit) Programmable High Speed Magnetic Rotary Encoder

Two digital absolute outputs (8.5 bit):

1 General Description

- Serial interface

- PWM output

The AS5132 is a contactless magnetic rotary encoder for accurate

angular measurement over a full turn of 360 degrees. It is a system-

on-chip, combining integrated Hall elements, analog frontend and

digital signal processing in a single device.

Incremental output with adjustable number of pulses

BLDC Output UVW, selectable for 1,2,3,4,5,6 pole pairs

Supports external PWM clock mode

To measure the angle, only a simple two-pole magnet, rotating over

the center of the chip is required.

Static and dynamic pre-commutation feature

User programmable zero position and sensitivity

High speed: up to 72,900 rpm

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 serial output over the

interface and as a pulse width modulated (PWM) signal.

Direct measurement of magnetic field strength allows exact

determination of vertical magnet distance

An additional U,V,W output can be used for a block commutation for

a brushless DC motor. An incremental signal is available as an

option.

Incremental Outputs ABI Quadrature: 90ppr, step direction:

180ppr, fixed pulse width 360ppr

In addition to the angle information, the strength of the magnetic field

is also available as a 5-bit code.

9-bit multi turn counter

Wide magnetic field input range: 20 – 80 mT (typical)

Wide temperature range: -40ºC to +150ºC

Thin Small Pb-free package: SSOP 20

Fully automotive qualified to AEC-Q100, grade 0

A software programmable (OTP) zero position simplifies assembly

as the zero position. The magnet does not need to be mechanically

aligned.

2 Key Features

360º contactless angular position sensing

3 Applications

The AS5132 is suitable for contactless rotary position sensing, rotary

switches (human machine interface), AC/DC motor position control

and Brushless DC motor position control.
