Because the evaluation board has footprints for isolated gate bipolar transistors (IGBTs) and MOSFETs in TO-263 or TO-252 packages, respectively, the ADuM3123 can be evaluated with many different power devices. REQUIRED DOCUMENTS SUPPORTED iCoupler MODELS The ADuM3123ARZ model represents a superset of the ADuM3123 models because it has the lowest minimum output voltage (4.4 V). The ADuM3123BRZ and ADuM3123CRZ models have minimum output voltages of 7.4 V and 11.1 V, respectively. ADuM3123ARZ ADuM3123BRZ ADuM3123CRZ Complete information about the ADuM3123 is available in the ADuM3123 data sheet, which should be consulted in conjunction with this user guide when using the evaluation board.

The layout includes the following components: To connect the evaluation board to a power supply, follow these steps:        VDD1 to GND1 must connect to a voltage source between 3.0 V and 5.5 V. A current limit setting of 25 mA is recommended, but a higher setting is also acceptable. VDD2 to GND2 must connect to a voltage source between 4.5 V and 18 V. A current limit setting of 200 mA is recommended, but a higher setting is also acceptable. The current draw depends on the switching speed and load being driven. GND1 and GND2 are isolated from each other. However, GND1 and GND2 can connect if the user desires. Ensure the power supplies connecting to each isolation region are floating but are not interacting with each other and can operate with the common mode introduced between the grounds (if there are any). INPUT/OUTPUT CONNECTIONS Resistor R4 is a 1206 pad that allows input termination if desired. Resistor R4 is unpopulated in the default state of the evaluation board, making VIA to GND1 a high impedance input. In the default state, the evaluation board must be driven with a high impedance output with a square wave between 0 V and VDD1 with respect to GND1. The source of Q1 is tied directly to GND2. The screw terminal marked GND2 can easily access the source of the Q1 device if needed. 14069-002  U1 is the footprint for the ADuM3123. C2 and C5 are 1 μF bypass capacitors; C1 is a 10 μF bypass capacitor. Q1 can be populated with TO-263 MOSFETs or TO-252 IGBTs (that is, MOSFETs) or only one package (that is, a TO263 MOFSET) with the footprint shown in Figure 2. Capacitor C3 is a 1206 pad available for load simulation capacitance. A typical value to test the evaluation board with is 2 nF. Resistors R1, R2, and R3 are 1206 pads provided for the user to place external series gate resistors to the load. A typical total resistance for the evaluation board is around 3 Ω. P2, a jumper pad, is available to aid in measuring peak current. A differential probe is recommended. Figure 2.
