For Shutdown (Fig22B) sequencing is initiated once UVP is activated. As long as the supplies do
not discharge too quickly, the shutdown sequence can be completed before the IRS2092S trips
UVP. Once UVP is activated, CSD and CStart are discharged at different rates. In this case,
threshold Ref2 is reached first and the preamp audio output is muted. It is then possible to
shutdown the Class D stage (CSD reaches two-thirds VDD). This process takes less than 200ms.

Conceptual Shutdown Sequencing of Power Supplies and Audio Section Timing
Fig22B
For any external fault condition (OTP, OVP, UVP or DCP – see “Protection”) that does not lead
to power supply shutdown, the system will trip in a similar manner as described above. Once the
fault is cleared, the system will reset (similar sequence as startup).
