The Mode1 and Mode0 pins are used to enable TDA7572. These perform the function of
bringing the IC out of standby (typically handled by a single standby pin on most audio IC's)
as well as determining if the I
occurs.
The Auto-mute Voltage pin is used to provide an under-voltage-lockout for the IC. Using a
resistor divider between V2P5 and SVR a series of comparator prevent the IC from power-
up further until sufficient voltage is present at VSP and SVR(equal to GND in the split supply
case. Once this voltage requirement is met, the chip is forced into mute (a special, direct
form of mute that does not use or act upon the MUTE pin) under a second, higher voltage
threshold is met. At this point the IC performs its normal power-up, controlled by the state of
the MODE pins and the various configuration pins. Refer to the under-voltage lockout
(UVLO) section of the documentation for details on these thresholds.
The Auto-mute Voltage pin is also used to provide an over-voltage shutdown based on
absolute voltage of VSP-VSM.
