TAS6424-Q1: OTSD Auto Recovery Register 0x21, bit 3

Jared Becker

Part Number: TAS6424-Q1

Hi Team,

For the OTSD Auto Recovery bit, should the Description say "1": Do not report overtemperature faults on the FAULT pin? Instead of the "0"..

Thank you,

Jared

Jared,

You are correct. This is a typo and we will correct on the next revision of the datasheet.

Hi Gregg,

One additional question.. if a value of 0 is entered for bit 3, does that also mean that Automatic Temperature Protection Recovery is non-active? Meaning the TAS6424-Q1 will not automatically recover if the die temperature drops below the OTW threshold, ultimately requiring a reset of the device to get it working again?

Thanks,

Jared

Jared,

Correct. If the bit 3 is "0" then the automatic recovery is not active.

For recovery, one needs to clear the faults, by asserting Bit 7 in Register 0x21.

Hi Gregg,

Thank you for the response and also confirming that if an OTSD fault occurs, the fault registers will indicate that a fault occurred and hold that fault value of "1" even if the device auto recovers from OTSD.

Best,

Jared
