Layer Short Detection
The TB2923HQ may be properly connected to a load such as a 4-
speaker, but one of the speaker lines may
be shorted to ground through a low-impedance path. The TB2923HQ can detect such a condition.
Figure 6
Layer Short
As is the case with output DC offset detection, pin 25 is also activated when there is a short on one of the
speaker lines as shown above. The detection impedance is 2.5
(typ.).
This feature allows detection of a short-circuit through a low-impedance path other than the speaker
impedance. It helps to avoid speaker damage in case of anomalous system conditions and improve system
reliability.

The negative (

through a low-impedance path due to some irregularities.
