7.7.1 I
7.7.2 Legacy mode (pin ADSEL connected to ground)
7.6 Speaker protection
7.7 Standby and mute operation
7.8 Start-up and shut-down sequence
To prevent damage of the speaker when one side of the speaker is connected to ground, a
missing current protection is implemented. When in one channel the current in the high
side power is not equal to the current in the low side power, a fault condition is assumed
and the channel will be switched off. The speaker protection will be activated under the
following conditions:
The function of the STB pin is different in legacy mode and I
When the STB pin is LOW, the total quiescent current is low, and the I
be loaded.
When the STB pin is switched HIGH the TDA8595 is put in operating condition and will
perform a power-on reset, which results in a LOW-level DIAG pin. The TDA8595 will start
up when instruction bit IB1[D0] is set. Bit D0 will also reset the ‘power-on reset occurred’
bit (DB2[D7]) and releases the DIAG pin.
The soft mute and soft mute can be activated via the I
activated independently for the front channels (channel 1 and channel 3) and rear
channels (channel 2 and channel 4), and mutes the audio in 20 ms. The fast mute
activates the mute for all channels at the same time and mutes the audio in 0.1 ms.
Releasing the mute after a fast mute will be by a soft un-mute of approximately 20 ms.
When the STB pin is switched to Standby mode and the amplifier has started, first the fast
mute will be activated and then the amplifier will shut-down. For instance, during an
engine start, it is possible to fully mute the amplifiers within 100 s by switching the
STB pin to zero.
The function of the STB pin will change from standby/operating to standby/mute/operating
and the amplifier will start directly when the STB is put into mute or operating. Mute
operating is controlled via an internal timer (20 ms) to minimize mute-on pops. When the
STB pin is switched directly from operating to standby, first the fast mute will be activated
(switching to mute within 100 s) and then the amplifier will shut-down.
To prevent the amplifier producing switch-on or switch-off pop noise, the capacitor on the
SVR pin is used for smooth start-up and shut-down. Increasing the value of the SVR
capacitor will mean a longer start-up and shut-down time. The amplifier output voltage is
charged to half the supply voltage minus 1.4 V in mute condition, independent of the
I
where the output will reach half the supply voltage, is used to release the mute if the
I
stay in mute when the bits were set to mute (2.6 V < V
