TAS5825M: Latched up VR_DIG regulator

Part Number: TAS5825M


Hello,

Our customer build 240 units of ES1 boards using TAS5825M.

They found 2 pcs of TAS5825M VR_DIG pin is seems latched up at 0.6 V even PDN pin is asserted to High.

On the datasheet PVDD and DVDD are not required any power up sequence.

Power supply condition are DVDD= 1.8V and PVDD= 5.0V

Do you see any concern to create Latch up status of VR-DIG pin?

Regards,

Mochizuki
