Audio Car Stereo Audio Amplifier with TDA1553CQ


Posted on Feb 5, 2014

When a short-circuit to ground occurs, which forces a DC voltage across the loudspeaker of >= V, a built-in protection circuit becomes active and limits the DC voltage across the loudspeaker to <= V. Pin 12 detects the status of the protection circuit (e. g. for diagnostic purposes). If any output is short-circuited to ground during the standby mod

e, it becomes impossible to switch the circuit to the mute or operating condition. In this event the supply current will be limited to a few milliamps.
