7.4.3.3.3 SLEEP Transition 0→1
TPS38800-Q1 TPS388R0-Q1 SLEEP 0→1 Transition Figure 7-15 SLEEP 0→1 Transition

The TPS38800-Q1/TPS388R0-Q1 takes several actions on the SLEEP 0→1 transition:

  1. After SLEEP 0→1 transition:
    1. As each rail passes the MON's OFF threshold, automatically (and expected to happen within about 5-10 µs) the relevant UV and OV interrupts are unmasked and enabled/disabled according to the IEN_UVHF and IEN_OVHF registers.
  2. After a SEQ_TOUT has expired.
    1. TPS38800-Q1/TPS388R0-Q1 enters the ACTIVE state and TPS38800-Q1/TPS388R0-Q1 continues normal monitoring in accordance with the IEN_UVHF and IEN_OVHF registers.
