Short-Circuit Protection and Fault-Reporting Circuitry

3.1Short-Circuit Protection and Fault-Reporting Circuitry

The TAS5152 is a self-protecting device that provides fault reporting (including high-temperature protection and short-circuit protection). The TAS5152 is configured in back-end auto-recovery mode and, therefore, resets automatically after all errors (M1, M2, and M3 are set low). This means that the device restarts itself after an error and reports shortly through the SD error signal.

3.2Fault Reporting

The OTW and SD outputs from the TAS5152 indicate fault conditions. Please refer to the TAS5152 Data Manual for a description of these pins.

The temperature warning signals at the TAS5518-5152K8EVM board are wired-OR to one temperature warning signal (OTW– pin 22 in the control interface connector). Shutdown signals are wired-OR into one shutdown signal (SD– pin 20 in the control interface connector).

The shutdown signals will activate with the temperature warning signal to give chip-state information as described in Table 3-1. Device fault-reporting outputs are open-drain outputs.°
