The TMAG5273 is a 3-Axis (3D) linear Hall effect sensor designed for wide range of industrial and personal electronics applications. This device integrates 3 independent Hall sensors in X, Y, and Z axes. A precision analog signal-chain along with integrated 12-bit AD converter digitizes the measured analog magnetic field values. The I2C interface, while supporting multiple operating VCC ranges, ensures seamless data communications with low-voltage microcontrollers. The device integrated temperature sensor data is available for multiple system functions, such as thermal budget check or temperature compensation calculation for a given magnetic field.

The TMAG5273 can be configured to enable any magnetic fields and temperature measurements at any order required for a particular application. The device supports user defined interrupt and conversion trigger functions either through a dedicated INT pin, or through I2C line. Threshold detection features, along with wake up from sleep mode, enable flexible system design to optimize speed versus power consumption. Multiple diagnostics features enhance system design robustness and data integrity.

The device is offered in two different orderables for separate magnetic field ranges. Each orderable part can be configured further to select one of two magnetic field ranges that suits the magnet strength and component placements during system calibration. The high level of integration provides flexibility and cost effectiveness in a wide array of sensing system implementations.

The device performs consistently across a wide ambient temperature range of –40°C to +125°C.
