Event

Conditions (all mandatory)

Main Battery

becomes Valid with

Input Power Source

( VBAT rising,

VBAT > LOWBAT)

 ADPWAKEEN or USBWAKEEN is set

 VSYS valid.

 Battery already present (SBATDET=1, not an insertion event)

 AC/DC Adapter (SVDCINDET=1 when DCBOOT=0) or USB already inserted

(SVBUSDET =1)

– BATLOW_B was initially “0” when external power was plugged

then be

comes “1” after battery has been charged up, prevents case where battery

voltage may float up due to cell “relaxing” during SOC G3.

Power Button

Pressed

 VSYS valid

 VBAT valid (SBATDET=1 and BATLOW_B=1 if BATRMPDEN set, or BATLOW_B=1

if BATRMPDEN cleared)

Table 17: Truth Table of Cold Boot Triggers

All the conditions in the table above shall be met for Cold Boot (wakeup) to occur. For example, wakeup with

AC/DC adapter insertion but without a battery can only occur when all these conditions are met: SVDCINDET=1

(AC/DC adapter insertion), ADPWAKEEN=1, BATLOW_B=1 (which means DCBOOT=1), BATRMPDEN=0.

Without a battery, USB power source insertion cannot cause the system to boot.
