I2C bus interface
TDA7575B
Doc ID 14103 Rev 2
5.6
I2C abilitation setting
It is possible to disable the I2C interface by acting on I2C pin (pin 16) and control the
TDA7575B by means of the usual standby and mute pins. In order to activate or deactivate
this feature, I2C pin must be set as follows:
●
I2C pin (pin 16) < 1.5V: I2C bus interface deactivated
●
I2C pin (pin 16) > 2.5V: I2C bus interface activated
It is also possible to let I2C pin floating to deactivate the I2C bus interface, or to short I2C pin
to VCC to activate it.
In particular:
●
I2C enabled: I2C pin (pin 16) > 2.5 V
–
STD mode: Vst-by (pin 5) > 3.5 V, IB2(D1)=0
–HE mode: Vst-by (pin 5) > 3.5 V, IB2(D1)=1
–
Play mode: Vmute (pin 4) >3.5 V, IB1 (D2) = 1
The amplifier can always be switched off by putting Vst-by to 0V , but with I
2C enabled it can
be turn on only through I2C (with Vst-by > 3.5 V).
●
I2C disabled: I2C pin (pin 16) < 1.5 V
–
STD mode: 3.5V < standby (pin 5) < 5
–HE mode: Vstby (pin 5) > 7 V
–
Play mode: Vmute (pin 4) > 3.5 V
For both STD and HE mode the play/mute mode can be set acting on Vmute pin.
When I2C bus is disabled, when a fault is detected pin 14 (CD-OUT) is pulled down by the
internal logic circuitry. The faults detected are the short circuit to ground, to VCC and across
the load (after an aver current detection).
