Description

The TMAG5170D-Q1 is a fully redundant, electrically isolated dual die 3D hall effect sensor with a precision signal chain. The two dies are vertically aligned providing superior matching output results with each die being independently configurable, including temperature sensing with temperature drift compensation. Multiple measurement types are supported included 1D linear, 2D angle, 3D joystick and magnetic threshold cross applications.

The TMAG5170D-Q1 contains on-chip diagnostic features required for high reliability automotive and industrial applications, including monitors of both internal and external fault conditions. The device supports multiple power options such as wake-up and sleep mode, allowing designers to optimize system power consumption based on system-level needs.

Integrated angle calculation engine (CORDIC) provides full 360° angular position information for both on-axis and off-axis angle measurements with magnetic gain and offset correction to mitigate the impact of system mechanical error sources. The integrated ALERT function can be used to generate interrupt with either sensor conversion, magnetic threshold cross, or functional safety violation.
