3.2 Fault Reporting
Protection
The OTW and SD outputs from the TAS5176 indicate fault conditions. Refer to the TAS5176 data manual
for a description of these pins.
Table 3. TAS5176 Warning/Error Signal Decoding
OTW SD Device Condition
0 0 High temperature error and/or high current error
0 1 High temperature warning
1 0 Under voltage lockout or high current error
1 1 Normal operation, no errors/warnings
The temperature warning signals at the TAS5176DDW6EVM board are wire-ORed to the temperature
warning signal ( OTW – pin 22 in the control interface connector).
Shutdown signals are wire-ORed into the shutdown signal ( SD – pin 20 in the control interface connector).
The shutdown signals will together with the temperature warning signal provide chip state information as
described in Table 3 . Device fault reporting outputs are open-drain outputs.
