... NXP Semiconductors Table 4. Interfacing SO/OL connected to: V SSD(HW) Open The device has two modes: Sleep and Operating. In Sleep mode the TFA9815 is not biased and has a very low supply current. Sleep mode can also be used to quickly mute the device. When the TFA9815 is set into Operating mode the device is started via the start-up sequence, which provides a pop-free start-up behavior ...
