TAS6511-Q1: Real-time Load Diagnostic

Leo Syu

Part Number: TAS6511-Q1

Tool/software:

Hi TI expert:

I powered up the TAS6511 and set it to PLAY mode. I also enabled the Real-time Load Diagnostic in the RTLDG_CONTROL0 Register.

However, when I removed the speaker, the real-time diagnostic did not seem to work. I checked the RTLDG Fault Mem Register (Address = 0x8B), and the amplifier did not detect an open load.

Could you please assist me in resolving this issue?

Thanks.

Leo.

I follow the data sheet, session 8.3.5.1.2 Automatic DC load diagnostics during Hi-Z or PLAY to verify real-time diagnostic. But it doesn't work.

Hi Leo

You should also enable pilot tone, and set SL/OL, S2G/S2P threshold.

You can send e-mail to me, I can send one guide to you. My e-mail: derek-gong@ti.com
