In TLF35584 PMIC IC, what's difference between WAKE & ENABLE signals?

For wake up if voltage at wake pin is greater than WAK, Hi, it will wake up the PMIC.

For enable, if voltage at enable pin is greater than ENA,thrhi, it will enable the PMIC.

For wake up, any pulse pattern required? Is it fine If continuous HIGH is applied to enable pin ?

 

Regards,

Abhishek

Hi Abhishek,

Thanks for your query.

The WAK and ENA input pins are battery voltage level capable. A signal, with a voltage higher than VWAK,hi applied
at pin WAK for tWAK, min represents a valid Wake-Signal.

A positive going edge at pin ENA with a rise time tENA, rise represents a valid Wake-Signal as well.
A valid Wake-Signal will bring the device from STANDBY to INIT state, from SLEEP to WAKE state or from
FAILSAFE to INIT state.
A low signal VWAK,lo at pin WAK as well as a negative going edge at pin ENA will have no impact on the state
machine and will not initiate a transition between states.

For more information, please check the state machine section in the datasheet.

Regards,

Kranthi
