DPSLP State

The DPSLP state is another low power operating mode

for the operating system. It is intended to be used in a

lower power configuration than the SLEEP mode. It is

similar to the SLEEP state, but DPSLP uses slightly dif-

ferent configurations to enter and exit this mode. Each

output can be programmed to be on or off in the DPSLP

state. This programming can be different and independ-

ent from the SLEEP state. The outputs follow their pro-

grammed sequencing delay times when turning on or

off as they enter or exit the DPSLP state.

The IC can enter DPSLP state via I2C register bit

DPSLP, I2C register bit DPSLP MODE, and a GPIO in-

put pin. The IC’s specific CMI determines the specific

combination of these three inputs to enter DPSLP state.

The I2C bit DPSLP MODE is set at factory and cannot

be changed by the user. It controls the logical combina-

tion of the GPIO input and the DPSLP register bit to en-

ter DPSLP state.

When DPSLP MODE is factory configured to 1, the log-

ical combination is an “OR” function and when DPSLP

is factory configured to a 0, the logical combination is an

“AND” function.

If no GPIOs are configured as a control input to enter

and exit DPSLP state then only the DPSLP register bit

controls the entry and exit of the DPSLP state.

Table 2a and 2b show the conditions to enter DPSLP

state. ACT88326’s I2C stays enabled in DPSLP state.

The IC exits the DPSLP state when the conditions to

enter DPSLP state are no longer present. Asserting

nPB low for > 32ms clears the DPSLP bit to 0 and the

PMIC exits DPSLP state.
