A33115 Precision TMR Angle Sensor

Allegro MicroSystems

360° angle sensor that provides high-resolution angular position information.
Allegro A33115 is a 360° angle sensor that provides high-resolution angular position information. It is based on magnetic sensing that combines TMR (Tunneling MagnetoResistance) and VH (Vertical Hall) technologies. The device's system-on-chip architecture includes two independent angle sensing channels, digital signal processing, and SPI, PWM, motor commutation (U, V, W), and encoder outputs (A, B, I).

Product Number: A33115KLEATR

Class: Angle Sensor

Tag: TMR Angle Sensor, Motion & Position Sensors

Primary TMR channel capable of 14-bit noise-free resolution.
Secondary channel capable of 10-bit noise-free resolution.
Wide operating voltage (3.7 to 18 V) enables direct connection to a vehicle battery
Low Power Mode, where the IC monitors and maintains turn count of the magnet in a key-off condition.
Linearization to reduce error from misalignment between the sensor and target magnet.
AEC-Q100 grade 1.
Designed to meet ASIL D requirements when used in conjunction with appropriate system-level control.
