SLYS054B March 2024 – August 2024 TMAG5213
PRODUCTION DATA
After applying VCC to the TMAG5213 device, ton must elapse before the OUT pin is valid. During the power-up sequence, the output is Hi-Z. A pulse as shown in Figure 7-4 and Figure 7-5 occurs at the end of ton. This pulse can allow the host processor to determine when the TMAG5213 output is valid after start-up. In Case 1 (Figure 7-4) and Case 2 (Figure 7-5), the output is defined assuming a constant magnetic field B > BOP and B < BRP.
If the device is powered on with the magnetic field strength BRP < B < BOP, then the device output is indeterminate and can either be Hi-Z or pulled low. During the power-up sequence, the output is held Hi-Z until ton has elapsed. At the end of ton, a pulse is given on the OUT pin to indicate that ton has elapsed. After ton, if the magnetic field changes such that BOP < B, the output is released. Case 3 (Figure 7-6) and Case 4 (Figure 7-7) show examples of this behavior.
