TAA5242: shutdown time

Toshiro Imi

Part Number: TAA5242

Tool/software:

Hi,

Our customer has a question what kind of issue will be happened in case t4, t5, t6 shown in Figure 7-4 sets less than 10ms.

It seems TAA5242 turn to shutdown sequence i.e. volume ramp down, power down in digital and analog block, turning into low power mode in this preiod.

best regards,

Hi Imi-san,

If the 10ms is not given, then the device may not shut down properly and will not go into its proper low power state. If this happens you may observe higher than expected current consumption.
