2.1 EVM Setup and Operation

Basic EVM Setup

This section describes the setup and operation of the EVM for parameter performance evaluation. Figure 3-1 shows a typical test configuration of the ISOM8610 Opto-Emulator EVM.

The simplest EVM setup is to test using a 5V input with and a 5VSRC. However, the input resistor is sized to accommodate up to 24V logic inputs. ISOM8610DFGEVM has do not populate (DNP) footprints for components which can be populated to apply different test conditions to the device. Section 2.1 lists and describes possible test configurations that can be achieved by modifying different components on the EVM.

Table 2-1 Component Configurations
ComponentDescription
R1, R2 R1 is sized for 5V - 24V operation. If a larger supply or smaller value is needed, then select a resistor that provides the desired IF current to the anode.
R3, R4 R3 is a short for normal operation. The footprint is provided to allow versatile test configurations for the user.
J1, J7J7 provides a place to quickly short the cathode to ground. Additional ground connections can be found on J1.
J3 Short J3 and Remove J4 to use the output as a high side switch.
J4 Remove J3 and Short J4 to use the output as a low side switch.
C1C1 can be used to add capacitance to the input diode.
