7.3.4 Sampling Rate

When the TMAG5328 device powers up, the device measures the first magnetic sample and sets the output within the tON time. The output is latched, and the device enters an ultra-low-power sleep state. After each tActive time has passed, the device measures a new sample and updates the output if necessary. If the magnetic field does not change between periods, the output also does not change.

While in active mode, the part will go through different steps. The content of the OTP (One-Time-Programmable Memory) is loaded first, and this steps takes about 35 µs and consumes around 350 µA. For the next 5 µs, the current source will be started and settled. The part now consumes around 650 µA in this step. Finally, the part conducts the Hall sensor conversion for about 25 µs and consumes the peak current of around 2 mA.
