At the onset of clipping of one or more output stages, the
dynamic distortion detector becomes active and pin 12
goes low. This information can be used to drive a sound
processor or DC volume control to attenuate the input
signal and thus limit the distortion. The output level of
pin 12 is independent of the number of channels that are
clipping (see Fig.3).

S HORT - CIRCUIT PROTECTION
During this short-circuit condition, pin 12 is low for 20 ms
and high for 50
When a short-circuit occurs at one or more outputs to
ground or to the supply voltage, the output stages are
switched off until the short-circuit is removed and the
device is switched on again, with a delay of approximately
20 ms, after removal of the short-circuit. During this
short-circuit condition, pin 12 is continuously low.
When a short-circuit across the load of one or both
channels occurs the output stages are switched off during
approximately 20 ms. After that time it is checked during
approximately 50
m
s (see Fig.4).
The power dissipation in any short-circuit condition is
very low.
T EMPERATURE DETECTION
When the virtual junction temperature T vj reaches 150 ° C,
pin 12 will become continuously low.
s to see whether the short-circuit is still
present. Due to this duty cycle of 50 m s/20 ms the average
current consumption during this short-circuit condition is
very low (approximately 40 mA).

O PEN COLLECTOR OUTPUT
Pin 12 is an open collector output, which allows pin 12 of
more devices being tied together.
