3 Description

The TMAG6181-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 sensors at X and Y

axes that are used to keep track of rotations.

The TMAG6181-Q1 features a wide operating

magnetic field (20mT – 1T) that enables flexible

mechanical placements as well as low latency (< 2μs)

outputs for high-speed applications like rotor position

sensing. The fast start-up time (<40μs) enables low

power applications by using a sleep pin that enables

the device to enter two low power modes: sleep mode

and a low power turns counting mode. An integrated

turns counter keeps track of the number of rotations,

and the turns counter value is transmitted using PWM

on the TURNS pin.

The TMAG6181-Q1 offers extensive diagnostics and

is designed for Functional Safety applications. The

device performs consistently across a wide ambient

temperature range of –40°C to 150°C with minimal

thermal drift and lifetime errors.
