Hi,

TSC2046E has two different supply pins - VCC and IOVDD.

Is there any power on sequence requirement for these supplies or can they be powered on in any sequence?

Regards,

Vini

    Vini,

    Indicated in the TSC2046 d/s that "IOVDD must be <= VCC". Thus, Vcc should be power up first, or simultaneously with IOVDD.
