TPA3131D2: High current drawn upon start up.

Part Number: TPA3131D2

Hi,

We noticed current as high as 1.9A was drawn upon start up with BTL mode under 4ohm load. The same result happened on EVM as well. It gradually drop to 1.5A within 3 seconds. This is with 300mV input and more severe at 1V input. Is this behavior normal? Why it could happen?

Thanks.
