Description

Top Features

Packaging

The A33110 is a 360° angle sensor ICs that provide contactless high-resolution angular position information based on magnetic sensing that combines TMR (Tunneling MagnetoResistance) and VH (Vertical Hall) technologies.

The device is a system-on-chip (SoC) architecture that includes two independent angle sensing channels, digital signal processing, and output options: SPI, PWM, motor commutation (U, V, W), and encoder outputs (A, B, I).

Also integrated into the devices are on-chip EEPROM technology, capable of supporting a high number of read/write cycles for flexible end-of-line programming of calibration parameters.

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 vehicle battery
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

14-pin TSSOP (suffix LE)
