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.
