EVALUATION BOARD HARDWARE POWER SUPPLIES The EV-AD74413RSDZ comes with a single power supply connector that directly powers the AVDD pin of the AD74413R. Set the AVDD supply as described in the AD74413R data sheet.
The EV-AD74413RSDZ AVDD supply powers an on-board regulator (ADP2360) that generates a 5 V supply to the EV-AD74413RSDZ (see Figure 2). Use the 5 V supply for the following purposes:
• To power a 2.5 V external reference (ADR4525). The ADR4525 can be used as an alternative to the AD74413R on-chip reference.
• To power a 3.3 V regulator (ADP1720). The 3.3 V from the regulator powers the DVCC and IOVDD supplies of the AD74413R.
Figure 2 shows a simplified drawing of the power connections on the EV-AD74413RSDZ.
REFERENCE OPTIONS By default, the EV-AD74413RSDZ uses the AD74413R on-chip reference by shorting the REFOUT pin to the REFIN pin. There is also an external reference option (ADR_REF) available on the EV-AD74413RSDZ. The ADR4525 can be used as an external reference instead of using the internal reference. Connect the appropriate jumpers if using the external reference. See Table 1 for the specific link options and functions.
OUTPUT CHANNELS The AD74413R has four channels, see the AD74413R data sheet for more information. Figure 13 shows the schematic details for all four channels.
There are four channel screw terminal connectors on the EV-AD74413RSDZ. These terminal connectors, CH_A, CH_B, CH_C, and CH_D, connect the desired loads to the four AD74413R channels.
SPI COMMUNICATION The SDP-S board handles the communication to the EV-AD74413RSDZ via the PC. By default, the SDP-S board controls the SPI communication, the RESET pin (driven high), and LDAC pin (driven low). The SDP-S board also monitors the ALERT pin, ADC_RDY pin, and the GPO_x pins of the AD74413R.
A reset button (S1) is available on the EV-AD74413RSDZ.
The EV-AD74413RSDZ supports using an Arduino® board (such as the EVAL-ADICUP3029) when connected to the headers provided on the EV-AD74413RSDZ. See Table 1 for the necessary links to the Arduino header.
TEST POINTS The EV-AD74413RSDZ has multiple test points. Debug access is available for all AD74413R pins and all four channel screw terminals. The test points are located adjacent to the relevant pins on the AD74413R.
LINK CONFIGURATION OPTIONS Set the JPx and Px jumpers correctly to properly operate the EV-AD74413RSDZ before using this board. The functions and default states of these options are listed in Table 1.
Before applying power and signals to the EV-AD74413RSDZ, ensure that all links are set to the default positions defined in Table 1.

EXAMPLE SEQUENCE This section provides an example showing how to configure the AD74413R for a selected function. Consult the AD74413R data sheet when programming the AD74413R.
Force Voltage Measure Current Example
In this example, the AD74413R is configured in voltage output mode and sources 11 V across the Channel A screw terminals with the CH_A connector. This example also shows how to measure the corresponding current through the sense resistor (RSENSE) using the on-chip, analog-to-digital converter (ADC). The ADC measurement is completed using a conversion rate of 20 SPS with 50 Hz and 60 Hz rejection enabled. See Table 2 for the full list of commands.
Place a suitable load across the Channel A screw terminals by using the CH_A connector. Refer to the AD74413R data sheet for the recommended load range in voltage output mode.
To complete the register write steps shown in Table 2 with the AD74413R software GUI, take the following steps:
1. In the Configure tab, use the dropdown menus to select Actuators and Voltage Output (see Figure 4).
2. In the advanced settings window (see Figure 5), set the DAC Code slider to 8191 (11 V).
3. Click Apply. Clicking this executes all writes required to configure the device and to enable ADC conversions in default mode. This configuration allows the AD74413R to measure voltage across RSENSE in the 0 V to 2.5 V range at a 20 SPS conversion rate.
4. Click the View Results tab to view the ADC results.
See Figure 10 for a script example that executes the AD74413R commands described in Table 2.

DISCRETE DIGITAL OUTPUT CIRCUITS The EV-AD74413RSDZ evaluation board has four digital output circuits that are adjacent to the channel screw terminals. The circuits are an example of how the ADM1270 hot swap controller can implement a digital output circuit with the AD74413R.
Table 1 describes the required jumper connections for digital output operation.
Figure 14 shows the schematic for the digital output circuits. The circuits use the ADM1270 and are powered from the AVDD supply.
The current limit is set by the 100 mΩ sense resistor and the voltage at the ISET pin. Connecting the ISET pin directly to the VCAP pin sets the circuit current limit to 500 mA. The current limit is adjusted by either changing the value of the sense resistor or by applying a voltage to the ISET pin using a voltage divider to the VCAP pin. Consult the ADM1270 data sheet when using the digital output circuit.
When the ADM1270 is enabled with the AD74413R GPO_x pin, the ADM1270 controls the gate voltage of the external FET FDMC86139P while monitoring the voltage across a 100 mΩ sense resistor.
The current through the external FET is passed to the channel screw terminal, I/OP_x. The ADM1270 turns off the FET after a short delay when an overcurrent fault is detected. The capacitor on the TIMER pin sets the current limit time to approximately 66 µs.
The automatic retry function allows the ADM1270 to turn on the FET after detecting an overcurrent. The capacitor on the TIMER_OFF pin generates a delay before automatically trying to turn the FET on. The automatic retry function is only activated if the 0 Ω links (JP17, JP10, JP20 and JP22) are in place. The capacitor on the TIMER_OFF pin sets the fault current limit off time to approximately 100 ms.
Undervoltage and overvoltage monitors are also available on the digital output circuit and are set to approximately 14 V and 35 V, respectively, using a voltage divider configuration on the ADM1270 UV and OV pins.
Any PFET selected for this circuit contribute leakages to the I/OP_x screw terminal. This leakage can affect the accuracy of other analog functions, particularly at higher temperatures (depending on the chosen PFET and leakage profile). Consider the required accuracy of the analog function when implementing this circuit.
Users must, and can, verify their specific digital output load condition is supported by carrying out load specific testing with the digital output circuit.
Using the Digital Output Circuits
To control the digital output circuits with the AD74413R, insert the appropriate jumpers as defined in Table 1.
Configure the corresponding AD74413R GPO_x pin to be controlled by the GPO_DATA bit by setting the GPO_SELECT bit in the GPO_CONFIGx register to use the logic state set by the GPO_DATA bit.
Setting the GPO_SELECT bit allows the AD74413R to enable the digital output circuits. Set the GPO_DATA bit in the GPO_CONFIGx register to 1 to enable the digital output circuit and set the bit to 0 to disable the digital output circuit.
After a channel is enabled, the channel attempts to source current up to approximately 500 mA from AVDD to the associated screw terminal.
