Description

TMR3365 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 TMR3365 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 selfdiagnostic and alarm function, providing safety

assurances.

The TMR3365 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 TMR3365 is available in SOP8 package.
