Part Number: TPS8804

Tool/software:

Good day TI Team,

Summary: Please provide possible option to put AFE in sleep/standby mode and wakeup option from standby.

Details:

We are trying to put TPS8804 into standby mode, based on input at section 6.5(INPUT VOLTAGE AND CURRENTS- I stand-by) of TPS8804 datasheet.

Do we have any register configuration option to put TPS8804 in standby mode?

and

How can we wake up the TPS8804 in standby mode?

 

As of now we are giving 5.6V input to TPS8804 and 3.3V to MCU. 

Please guide us regarding steps to be followed to put TPS8804 in standby mode and retrieve from standby mode?

 

Thanks

Selvam

    TPS8804 has enable/disable bit to activate each function. By disabling all functions, current consumption can be lowered (standby current).   Register address 6h to Dh have bits to disable the functions. Unused functions can be disabled for lowering current consumption and enable the functions when necessary.
