This chapter describes the TAS5086-5186V6EVM board in regards to power supplies and system interfaces. Power Supply (PSU) Interface (J901) The TAS5086-5186V6EVM module must be powered from external power supplies. High-end audio performance requires a stabilized power supply, with low ripple voltage and low output impedance. Note: The length of power-supply cable must be minimized. -

Chapter 3 SLEU073 – JULY 2006 Protection This chapter describes the short-circuit protection and fault-reporting circuitry of the TAS5142 device. Short-Circuit Protection and Fault-Reporting Circuitry The TAS5142 is a self-protecting device that provides device fault reporting (including high-temperature protection and short-circuit protection). The TAS5186A is configured in back-end auto-recovery mode and, therefore, resets automatically after all errors. - Page 12 www.ti.com Device Fault Reporting Protection SLEU073 – JULY 2006 Submit Documentation Feedback...
