AS5145H/AS5145A/AS5145B

12-Bit Programmable Magnetic Rotary Encoder

Three incremental outputs

1 General Description

The AS5145 is a contact less magnetic rotary encoder for accurate

angular measurement over a full turn of 360 degrees.

Quadrature A/B/I (10 or 12 bit) and Index output signal (pre-

programmed versions available AS5145A for 10-bit and

AS5145B for 12-bit)

It is a system-on-chip, combining integrated Hall elements, analog

front end and digital signal processing in a single device.

User programmable zero position

Failure detection mode for magnet placement, monitoring, and

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.

loss of power supply

Red-Yellow-Green indicators display placement of magnet in Z-

axis

The absolute angle measurement provides instant indication of the

magnet’s angular position with a resolution of 0.0879º = 4096

positions per revolution. This digital data is available as a serial bit

stream and as a PWM signal.

Serial read-out of multiple interconnected AS5145 devices

using Daisy Chain mode

Tolerant to magnet misalignment and gap variations

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

An internal voltage regulator allows the AS5145 to operate at either

3.3V or 5V supplies.

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

Small Pb-free package: SSOP 16 (5.3mm x 6.2mm)

2 Key Features

Contact less high resolution rotational position encoding over a

3 Applications

full turn of 360 degrees

The device is ideal for industrial applications like contactless rotary

position sensing and robotics; automotive applications like steering

wheel position sensing, transmission gearbox encoder, head light

position control, torque sensing, valve position sensing and

replacement of high end potentiometers.

Two digital 12-bit absolute outputs:

- Serial interface

- Pulse width modulated (PWM) output
