The AS5161 is a contactless Hall-based magnetic position sensor for very accurate angular measurement over a full turn of 360°.
A sub range can be programmed to achieve the best output characteristic for the application. A simple diametrical 2-pole magnet rotating on the center of the IC is required: the magnet may be placed above or below the IC.
14-bit core resolution for fine user programming of the start and stop position
12-bit resolution PWM output signal
User programmable clamping, diagnostic levels and transition point
Multiple slope output characteristic
Overvoltage, short-circuit and reverse battery protections
High driving capability of resistive and capacitive loads
Broken GND and VDD detection over a wide range of different load conditions
Simple programming by provided programming hardware and software
Failure detection mode for magnet placement monitoring and loss of power supply, indication of high voltage condition
Wide temperature range: -40°C to +150°C
Height control in chassis ride
Pedal position sensing
Throttle position sensing
Transmission gearbox position sensor
Valve position sensing
