8.3.4 Power-On Time

Figure 8-4 shows the behavior of the device after the VCC voltage is applied and when the field is below the BOP threshold. When the minimum value for VCC is reached, the TMAG5124-Q1 will take time tON to power up and then time td to update the output to a high level.

Figure 8-5 shows the behavior of the device after the VCC voltage is applied and when the field is above the BOP threshold. When the minimum value for VCC is reached, the TMAG5124-Q1 will take time tON to power up and then time td to update the output to a high level.

The output value during tON is unknown in both cases. The output value during td will be set at high.
