Description



Features:

- Contact-less high resolution encoding over a full turn of
360 degrees
- Flexible system due to user programmable incremental
output modes:
- 10, 9, 8 or 7 bit user programmable resolution
- Quadrature A/B and index output signal
- Single channel output and direction indication
- U-V-W commutation signals for brush-less DC motors
- Absolute angular position mode:
- 10-bit resolution providing 1024 absolute positions per 360 degrees (step size ~ 0.35 deg)
- Synchronous serial interface (SSI) output for absolute position data
- Pulse width modulated (PWM) output, duty cycle proportional to angle
- User programmable zero / index position
- Failure detection mode for magnet placement monitoring
- Rotational speeds up to 10,000 rpm (incremental output)
- Push button functionality detects movement of magnet in Z-axis
- Two supply voltages: 3.3 V or 5 V

Description

The AS5040 is a system-on-chip, combining integrated Hall elements, analog front end and digital signal processing in a single device. It provides incremental output signals and the absolute angular position of a magnet that is placed either above or below the device.

The AS5040 can be configured to specific customer requirements by programming the integrated OTP (one time programmable) register. An internal voltage regulator allows the AS5040 to operate at either 3.3 V or 5 V supplies.
