ZHCSNX1A October 2022 – November 2022 TPS38700
PRODUCTION DATA
If NRST_IN pin is enabled, it may be asserted while TPS38700 is in SLEEP state. To ensure proper power state synchronization with the rest of the system, TPS38700 will assert NRST while executing the Sleep exit sequence. The NRST signal is de-asserted when both RST_DLY delay time has passed since last ENx, and the NRST_IN signal is de-asserted (or the connected button is released).
It should be noted that although not depicted in the TPS38700 State Diagram, Figure 8-2, for clarity, this sequence applies also in case of WDT-initiated reset.
