3 Protection
3.1 Short-Circuit Protection and Fault Reporting Circuitry
3.2 Fault Reporting
Protection
This chapter describes the short-circuit protection and fault reporting circuitry of the TAS5142 device.
The TAS5142 is a self-protecting device that provides fault reporting (including high-temperatureprotection and short-circuit protection). The TAS5142 is configured in back-end auto-recovery mode andtherefore resets automatically after all errors (M1 and M3 are set low, M2 is set high); see the TAS5142Stereo Digital Amplifier Power Stage data sheet (SLES126 ) for further explanation. This means that thedevice will protect itself after an error condition and report the error through the SD error signal.
The OTW and SD outputs from the TAS5142 indicate fault conditions. See the TAS5142 Stereo DigitalAmplifier Power Stage data sheet (SLES126 ) for a description of these pins.
Table 3. TAS5142 Warning/Error Signal Decoding
OTW SD Device Condition
0 0 High-temperature error and/or high-current error0 1 High-temperature warning1 0 Undervoltage lockout or high-current error1 1 Normal operation, no errors/warnings
The temperature warning signals at the TAS5142DDV6EVM2 board are wired-OR to one temperaturewarning signal ( OTW – pin 22 in control interface connector). Shutdown signals are wired-OR into oneshutdown signal ( SD – pin 20 in control interface connector).
The shutdown signals, together with the temperature warning signal, give chip state information asdescribed in Table 3 . Device fault-reporting outputs are open-drain outputs.
