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.
