To maintain better control over the sampling instants and maintain low power consumption, digital linear Hall sensors such as TMAG5273, or TMAG3001 for space-constrained designs, allow the microcontroller to trigger conversions only when necessary. The TMAG5273 can be placed in a low power standby mode, where the microcontroller can trigger conversions using an INT pin or through the I²C command and have the sensor synchronized with the system needs. Figure 2-3, shows a typical application diagram for a 3D Hall effect sensor connected to a microcontroller. Figure 2-4 shows the timing diagram where the conversions are triggered by the microcontroller.
