8 Bit Programmable Magnetic Rotary Encoder

with Motion Detection & Multiturn

1 General Description

2 Key Features

ꢀ

360º contactless angular position encoding

The AS5130 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. The angle can be measured using

only a simple two-pole magnet rotating over the center

of the chip. The magnet may be placed above or below

the IC. The absolute angle measurement provides

instant indication of the magnet’s angular position with a

resolution of 8 bit = 256 positions per revolution. This

digital data is available as a serial bit stream and as a

PWM signal. The AS5130 can be operated in pulsed

mode (Vsupply=off), which reduces the average power

consumption significantly. During Vsupply=off, the

measured angle can be stored using an internal storage

achieves very low power consumption during polling of

the rotary position of the magnet. If the position of the

magnet changes, then the motion detection feature

wakes up an external system. The device is capable of

counting the amount of magnet revolutions. The multi

turn counter value is stored in a register and can be read

in addition to the angle information. Furthermore, any

arbitrary position can be set as zero-position. The

system is tolerant to misalignment, air gap variations,

temperature variations and external magnetic fields and

high reliability due to non-contact sensing.
