Hardware Control Pins
The TAS5414A and TAS5424A incorporate four discrete hardware pins for real-time control and indication of
device status.
FAULT pin: This active-low, open-drain output pin indicates the presence of a fault condition that requires the
TAS5414A and TAS5424A to go automatically into the Hi-Z mode or standby mode. When this pin is
asserted high, the device has acted to protect itself and the system from potential damage. The exact nature
of the fault can be read via I2C with the exception of faults that are the result of PVDD voltage excursions
above 25 Vdc or below 6 Vdc. In these instances, the device goes into standby mode and the I2C bus is no
longer operational. However, the fault is still indicated due to the fact that the FAULT pin is open-drain and
active-high.
CLIP_OTW pin: The function of this active-low pin is configured by the user to indicate one of the following
conditions: overtemperature warning, the detection of clipping, or the logical OR of both of these conditions.
The configuration is selected via I2C. During tweeter detect diagnostics, this pin also is asserted when a
tweeter is present.
MUTE pin: This active-low pin is used for hardware control of the mute/unmute function for all four channels.
Capacitor CMUTE is used to control the time constant for the gain ramp needed to produce a pop- and
click-free mute function. For pop- and click-free operation, the mute function should be implemented through
I2C commands. The use of a hard mute with an external transistor does not ensure pop- and click-free
operation, and is not recommended unless an emergency hard mute function is required in case of a loss of
I2C control. For proper pop- and click-free operation the minimum recommended value of CMUTE is 330 nF.
STANDBY pin: When this active-low pin is asserted, the device goes into a complete shutdown, and current
draw is limited to 2 mA, typical. This is pin typically asserted when the car ignition is in the off position. It can
also be used to shut down the device rapidly when certain operating conditions are violated. All I2C register
content is lost when this pin is asserted. The I2C bus goes into the high-impedance state when the
STANDBY pin is asserted.
