3 Description

The TMAG6180-Q1 is a high-precision angle sensor

based on Anisotropic Magneto Resistive (AMR)

technology. The device features integrated signal

conditioning amplifiers and provides differential sine

and cosine analog outputs related to the direction of

the applied in-plane magnetic field. This device also

features two independent Hall sensor outputs at X

and Y axes that can be used to extend the angle

range of the sensor to 360°.

The TMAG6180-Q1 features a wide operating

magnetic field that enables flexible mechanical

placements as well as low latency (1.6μs) outputs

for high-speed applications like rotor position sensing.

The device features ultra-low latency on the sine

and cosine outputs to minimize latency related angle

errors and is designed for high-speed applications like

rotor position sensing up to 100krpm.

The TMAG6180-Q1 offers extensive diagnostics

to support stringent functional safety automotive

and industrial requirements. The device performs

consistently across a wide ambient temperature range

of –40°C to +150°C with minimal thermal drift and

lifetime errors.
