8.3.5 Power-On Time

Figure 8-5 shows the behavior of the device after the VCC voltage is applied and when the field is below the BOP threshold. Once the minimum value for VCC is reached, the TMAG5123-Q1 will take time tON to power up and then time tPD to update the output to a level High.

Figure 8-6 shows the behavior of the device after the VCC voltage is applied and when the field is above the BOP threshold. Once the minimum value for VCC is reached, the TMAG5123-Q1 will take time tON to power up and then time tPD to update the output to a level Low.

The output value during tON is unknown in both cases. The output value at the end of tON will be set at High.
