TAS5751MEVM: under voltage protection

Part Number: TAS5751MEVM
Other Parts Discussed in Thread: TAS5707

Dear all，

We have tested TAS5751M-EVM. Find that the UVL will not report error in 0X20 register. This result is not in accordance with the datasheet.

And we find that the UVL falling is 6V and UVL raising is 6.7V. The AVDD remains 3.3V when PVDD is falling to 6V.

Hi Ella,
You are right that the UV fault is actually NOT reported in the Error status register.

Hi Shawn

The TAS5707 can report UV error. Why the TAS5751 can not report the error? Is there any difference between the two device？
Thanks and best regards，
Ella

Ella,
They are using the different digital dies. It's not surprising that their behaviors are not the same.
