3.2 Fault Reporting
Protection
The OTW and SD outputs from TAS5162 indicate fault conditions. See the TAS5162 data sheet for a
description of these pins.
Table 3. TAS5162 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 Undervoltage lockout or high-current error
1 1 Normal operation, no errors/warnings
The temperature warning signals at the TAS5162DDV6EVM board are wired-OR to one temperature
warning signal ( OTW – pin 22 in control interface connector). Shutdown signals are wired-OR into one
shutdown signal ( SD – pin 20 in control interface connector).
The shutdown signals together with the temperature warning signal give chip-state information as
described in Table 3 . Device fault-reporting outputs are open-drain outputs.
