Hi Keiichi,

VCC1>VCC2 case is not a problem. The ISO1540/41 datasheet describes two sets of data, one for VCC1 and VCC2 both being in the 3.0V to 3.6V range, and the other for VCC1 and VCC2 both being in the 4.5V to 5.5V range. However, the device can be used with VCC1 and VCC2 independently in either range.

Rgds,

Anant
