Tool/software:
Hi Team,
I am working on IHP_IC platform where we are using TAS6584-Q1 Amplifier. Based on the customer requirements we must monitor the speaker fault like open load, shorted load, Short to Bat and Shor to GND once amplifier in play state.
Currently cyclic we are monitor short to GND and Short to Bat fault based on automatic DC diag and able to detect this two speaker fault. But OL/SL we are not ablet to detect using DC diag.
DC LDG Ctrl 1 Register (Address = 0xB0)
Based on Datasheet we have to enable the Real time diagnostic for speaker fault OL and SL for cyclic monitor.
We got real time diag document from TI and attached in mail.
1. In Doc page #5 mentioned but this offset 88 and 8C is not related to threshold value.
w C0 88 1D 00 00 00 # Write to offset 88, 32-bit wide, set Open load threshold e.g. ~40ohm
w C0 8C 00 C5 00 00 # Write to offset 8C, 32-bit wide, set Short load threshold e.g. ~1ohm
w C0 8C 00 C5 00 00 à Here 8C is register address and 4bytes 00 C5 00 00 is value correct?
I have attached pic here..
2.Based on Doc page #1 mentioned when RTLD detected then have to disabled the RTLD and again have to run the DC diag then its will be effect on play state channel output.
- Cyclic once amplifier in play state will be get same result for DC register C0 and C1 and RTLD register 8B and 8C for speaker fault?
4. we are not ablet to understand for page and book value actually not ablet to found the register 0x00 in datasheet.
w C0 00 00 # Return to page 0 of book 78
w C0 7F 8C # Change to book 8C. It's required to be in page 0 before changing a book
w C0 00 02 # Go to the page 02 in book 8C
Please Can you provide the required information its urgent for us.
