Hi TI Support Team,
The configuration of the amplifier remains default setting for all register so it begins PLAY mode for two channel.are active and used load is 4 ohm speaker. I read only 0x0C register for the aim. Let's consider 2 cases for open load detection:
CASE 1:
At the beginning the load is not connected to CH1 and the second load is connected CH2. Energized and then It can be monitored CH1 OL:Open load detected, CH2 OL: No Open load detected. After connecting the load to CH1, CH1 OL:No Open load detected. This CASE is OK.
CASE 2:
Both speakers are connected to the channels. After energizied the compenent,When I remove the one of the speakers in ANY TIME, It can not be monitored the OL states properly. The amplifier is continiued to report No open Load detected for both channel. I mean the DC Open load detection is working correctly for once at the beginnig but it doesn't work properly instantaneously. For detecting instantaneously should I use AC Load diagostic or is there any way? is there any API or libraries of the amplifier for the application software?
By the way I can not understand what Channel state DC diagnostics mode in 0x04 was. I tried the bit fields as changing to DC load Diagnostic and then read register 0x0C. But It didn't work :).
