serial command mode communication. Any configuration
change can be made on Register Settings tab.
(The following steps are used to verify functionality
of the devices.)
General Description of Software
When the GUI starts, it automatically detects which
device is connected to the PC and indicates that in the
status bar at the bottom-edge of the GUI. There are
two tabs available to control the EV kit. The System
tab provides system-level control of the selected output
pins, including static or dynamic PWM (Pulse-Width
Modulation) output in either serial or parallel Mode. The
Register Settings tab provides full control of the device,
including mode selection, per-channel configuration, and
enhanced diagnostics of the device. In Serial mode, the SPI
clock is set to 5MHz.
6) Select System tab.
7) Configure each input signal as Static High from the pull-
down menu, as shown in Figure 1.
8) Click on Drive Pins button on the left-side of the GUI.
9) Observe all the status LEDs (DS5 to DS12) light up,
and measured output voltages on corresponding
OUT_ test point match V
level.
DD
10) Change the input signal to Static Low from the
pulldown menu and observe as corresponding LED
turned off.
System Tab
The System tab allows driving the output pins by setting
up the input signal to the device through the on-board
USB to SPI/GPIO bridge IC, U4. Each input pin can be
configured as Static High, Static Low, Static PWM, or
PWM from the pulldown menu on the input lines in the
block diagram shown in the System tab. Refer to Figure 3.
11) Change the input signal to Static PWM. Select the
duty cycle from the pulldown menu, refer to Figure 2,
and observe the output on corresponding OUT_ test
point by oscilloscope.

Click Drive Pins button on the left-side of the GUI after
configuring the inputs. The outputs follow the state of the
inputs, while indicators connected to the OUT_ pins show
the static state or dynamic operation mode.
Register Settings Tab
The Register Settings tab is used for detailed
configuration of the device to explore all the available
features in either parallel (SRIAL is low) or serial (SPI)
mode (SRIAL is high). SPI communication is also
available in parallel mode with the MAX14912. For
a detailed explanation of the features, refer to the
MAX14912/MAX14913 data sheet. The mode and pin
configuration can be set through the MAX14912 I/O pins
control group box on the right-side of the tab. Refer to
Figure 4. The pin set slide buttons allow the setting of the
input pins high or low, while the read status boxes provide
visual colored states of the input/output pins.
Connect the oscilloscope probe to OUT_ pin to see the
output signal in real-time.
In static PWM and PWM mode, the GUI generates a
1kHz (if SRIAL pin is high) or 20kHz (if SRIAL pin is low)
square wave. The level of modulation is selectable from
the pulldown menu from 0% to 100%. Refer to Figure 2.
In PWM mode, the signal is modulated by a selected
waveform. It can be either a sine wave with a selectable
phase, triangle, or sawtooth wave. Refer to Figure 3. The
modulation frequency is adjustable from 0Hz up to 60Hz
by pressing the + or - buttons. This feature is useful to
control small motors, including 3-phase motors, and actuators.
The EV kit supports a number of different devices, as
listed in Table 3.

User-Supplied SPI
Reverse-Voltage Protection
To evaluate the EV kit with a user-supplied SPI bus,
disconnect the board from the PC. Apply the user-
supplied CS, SCLK (CLK), MOSI (SDI) and MISO (SDO)
to the J25 header. Make sure the master ground is
connected to the J25.5 ground pin.
The EV kit has reverse-voltage protection circuitry built
on the return path of the supply current. During normal
operation, the Q1 nMOSFET is ON since the gate voltage
is about 7.5V higher than the source. Very low R
of
ON
Q1 MOSFET helps to minimize voltage drop and power
dissipation to a negligible level. If V becomes negative
with respect to the supply ground, the MOSFET is turned
off and disconnects the current path.
DD
The logic level of the external SPI host should be compatible
with the J13 shunt selection, (e.g., 3.3V or 5V). Use an
external VL logic supply to TP19 to support different logic
levels from 1.6V to 5.5V. In this case, J13 shunt should
be removed.
Stand-Alone Operation
The EV kit can work without connecting to a PC. In this
case, jumpers should set the inputs, refer to Table 1 for
proper shunt positions. In stand-alone operation, the
devices should be configured for parallel mode. It is
recommended to enable internal de-bouncing by placing
the J7 shunt for proper operation.
Daisy-Chaining
The two MAX1491X EV kits can be daisy-chained by
pairing J24 of board #2 and J23 of board #1 in order to
control 16 outputs through a single SPI host. The J26
jumper of board #1 must be set to 2-3 position and both
boards have to be powered from an external +24V. The
PC should be connected to board #1.
This EV kit comes with two assembly options:
The MAX14912EVKIT# comes with a MAX14912ATE+ in
a 56-pin TQFN package.
It is also required that board #2 has installed jumpers for
SPI communication: J9: 1-2, J5: 1-2, J6: 1-2, J12: 2-3,
and J11: 2-3.
The MAX14913EVKIT# comes with a MAX14913ATE+ in
a 56-pin TQFN package.
The daisy-chain feature is not supported by rev 1.0 GUI
and can be evaluated using user-supplied SPI interface.
Refer to the MAX14912/MAX14913 data sheet for daisy-
chain command description.
Both EV Kit variations use the same PCB and bill of materials,
and the only variation is the IC assembled at U1.
Table 3. Products supported with
MAX14912/MAX14913 EV kit
External +5V Power Supply
An external +5V voltage can supply to TP1, +5V_EXT. In
this case the internal dc-dc controller should be disabled
(BUKEN = low) by switching SW1 into off position.

Figure 4. Digital Output Driver EV Kit GUI. Register Settings Tab
The two tables on the left side of the tab are the register map (upper table) and bit-by-bit control and description table (lower table).
When the register is selected in upper table, the lower table gives the description of each bit and allows changing the register set-
tings using drop down menus for writable registers 0x00 to 0x03. The register setting can be changed directly in the register map
table by double clicking on the Value cell. Each data entry should follow by the “Enter/Return” button on the keyboard. The Value cell
accepts binary (0b), decimal or hex (0x) numbers and automatically convert them into binary format. The modified register changes
its color from black to red until the data will be actually written to the register. There are several write and read options available
through the corresponding control buttons on the upper right side of the GUI.
When the Auto Write button is selected, any data typed in, or selected through, the Setting pulldown menu will be automatically
written into the corresponding writable register. The button renamed to Stop Auto Write and auto write function can be canceled by
clicking on this button second time.
When the Auto Read button is selected, the write function is disabled and the GUI is constantly monitoring the status and fault
conditions of the device. Clicking a second time on the button, which becomes Stop Auto Read, allows canceling this operation.
The Read All button performs a read operation of all registers after each click.
When any fault conditions occur, they will set the bit(s) in the corresponding read-only registers 0x04 to 0x07. The fault conditions
should be carefully evaluated and removed externally (overvoltage/under voltage, overload, open load, etc.). After that, select the
Clear Fault Registers Upon Next Write check box and perform any write/read operation to clear fault bits.
The Write Modified button performs write operation to all modified registers after each click.
