Table 3. TAS5612/14 Warning/Error Signal Decoding

SD OTW1 OTW2 Device Condition

0 0 0 High temperature error and/or high current error

0 0 1 Under voltage lockout or high current error. 100°C temperature warning

0 1 1 Under voltage lockout or high current error

1 0 0 125°C temperature warning

1 0 1 100°C temperature warning

1 1 1 Normal operation, no errors/warnings

The shutdown signals together with the temperature warning signal, give the chip state information as

described in Table 3. Device fault reporting outputs are open-drain outputs.
