DS250DF230: Power Sequence Related

Part Number: DS250DF230

Tool/software:

Hi TI team,

READ_EN_N, INT_N, SCL& SDA are 3.3V tolerant.

Just wonder any concern if we supply 3.3V first before 2.5V VDD?

Thanks.

    Hi Alfred,

    This falls within the absolute maximum ratings of the device.  We would not expect damage from this condition.

    Please also note that exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.  Because of this, I would not recommend designing a system where 3.3V is supplied for an extended period without 2.5V.  I think this would not be the case in your system where 3.3V is supplied for a short period of time prior to 2.5V.

    Thanks,

    Drew
