2.1 Overview

The basic setup in Figure 2-1 has the two power supplies required to evaluate isolator performance with any combination of 3.3 V or 5 V on either side. If both sides are evaluated at the same supply voltage, only one power supply is required and can be used to power both sides of the EVM.

CAUTION:

Note that this EVM is for operating parameter performance evaluation only and not designed for isolation voltage testing. Any voltage applied above the 5.5-V maximum recommended operating voltage of the isolators may damage the EVM.

Please note that if the ISO1541 is used, providing an input signal on the SCL2 pin does not yield any output on SCL1, SCL1 remains pulled up to VCC1.
