The TMAG3001 is a low-power linear 3D Hall-effect sensor designed for a wide range of industrial and personal electronics applications. This device integrates three independent Hall-effect sensors in the X, Y, and Z axes. A precision analog signal-chain along with an integrated 12-bit ADC digitizes the measured analog magnetic field values. The I2C interface, while supporting multiple operating VCC ranges, allows seamless data communication with low-voltage microcontrollers.

The TMAG3001 can be configured through the I2C interface to enable any combination of magnetic axes and temperature measurements. Additionally, the device can be configured to various power options (including wake-up and sleep mode) allowing designers to optimize system power consumption based on their system-level needs. Multiple sensor conversion schemes and I2C read frames help optimize throughput and accuracy. A dedicated INT pin can act as a system interrupt during low power wake-up and sleep mode, and can also be used by a microcontroller to trigger a new sensor conversion. The device also features a configurable low power switch mode for magnetic or angle measurements.

An integrated angle calculation engine (CORDIC) provides full 360° angular position information for both on-axis and off-axis angle measurement topologies. The angle calculation is performed using two user-selected magnetic axes. The device features magnetic gain and offset correction to mitigate the impact of system mechanical error sources.

The TMAG3001 features an ADDR pin that can be used to have four different I2C addresses. Each orderable part can be configured to select one of two magnetic field ranges that suits the magnet strength and component placement during system calibration.

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