TAS5613 Ready LED Blinking

Other Parts Discussed in Thread: TAS5613

When the TAS5613 is first turned on (with reset low), the ready LED is solid for a few seconds and then it starts to blink.

What does the blinking mean?

Thanks..

Bruce, I have a few preliminary questions.

- Is this with our EVM?

- What is your power supply voltage? Is it stable?

- Please also check the 12V supply, across C64 or C65 in the EVM.

- What are the positions of SW1 and SW2, the BTL/PBTL switches?

Best regards,

Steve.

Steve,

Thanks for your reply. This is not with the EVM. It is with our own prototype.

Like you were inquiring... the power was not stable. Not the 12V though, the voltage regulator that powers our microcontroller that reports on TAS5613 status was thermally overloaded and cycling on and off. It was so steady at about 1 Hz that it looked like a status signal….

Thanks,

Bruce
