EVM Setup and Operation

The basic setup has two power supplies (TB1, TB2, P1-P4) to evaluate isolator performance with any

combination of 2.7 V, 3.3 V, or 5 V for VCC1 and VCC2. If both sides are to be 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 although these devices provide galvanic isolation of up to 3000 Vrms,

this EVM cannot be used for isolation voltage testing. It is designed for the

evaluation of device operating parameters only and may be damaged if a

voltage exceeding 5.5 V is applied anywhere in the circuit.

For the ISO7131, ISO7141, and ISO7142 isolators, JMP13 and JMP14 should be set to VCC1 and VCC2,

respectively, for normal operation.

For the ISO7140, JMP14 should be set to VCC2 for normal operation (JMP13 is not needed).
