8.3.3.1 Power Up

When ACT is driven high, the first EN signal is turned on by TPS38700S-Q1. Then, the MON voltage rises and triggers TPS389006-Q1 to send the first SYNC signal which causes TPS38700S-Q1 to turn on the second EN voltage. This process repeats until all Enable voltages turn on. After the final EN signal is turned on, NRST deactivates after the RST_DLY time. A successful power up sequence is shown in Figure 8-5 using the circuit shown in Figure 9-12. Note that the TPS389006-Q1 defaults to using UV thresholds for sending the SYNC pulse when sequencing up.
