TMR3366 Automotive Digital TMR Magnetic Angle Sensor
TMR3366 is a non-contact, high-speed, high-precision digital magnetic angle sensor from MultiDimension Technology (MDT). It captures the magnetic field signal and calculates the rotation angle by sensing the rotation of the magnet above the sensor. The sensor integrates a tunneling magnetoresistance (TMR) sensor and a signal processing ASIC, providing a rich set of working parameter configurations and various output interfaces for customers to choose from.
The TMR3366 provides three output modes: analog, PWM, and SENT (supports enhanced protocol). It can achieve the best absolute position angle detection performance when the magnetic field is in the range of 200 Gs to 800 Gs. The sensor has a built-in self-diagnostic and alarm function, providing safety assurances.
The TMR3366 features a built-in 5-point/17-point non-linear calibration function, which is simple to operate, allowing customers to easily compensate for non-linear errors caused by mounting. It also supports programmable angle measurement range functions to meet customer needs. The sensor supports a one-wire communication protocol (OWI).
The TMR3366 is available in SOP8 package.
