[FAQ] TPS650830: How Do I Enter Deep Sleep Modes DS4/5?

For Deep Sleep with V5A_DS3 on:

Write a '1' to either EC_SLP_S4 or EC_DS4 then, pull SLP_SUS# down to logic LOW. This will keep the V5A_DS3 on while SLP_SUS# is LOW.

To turn off V1.8A during Deep Sleep write a '00' to bits 0&1 of register V18ACNT, x34.
