Detailed Description of Software
User-Interface Panel
The program’s main window (Figure 2) is navigated by
using a mouse or a combination of the Tab and Arrow
keys. The MAX17065 EV kit software provides controls
for the following software-configurable features:
Frequency and Mode selection, ON Enables, Outputs
configuration, Faults detection, Current Limit settings,
and Manufacturer ID/Silicon Revision detection.
Changes to the controls result in a write operation that
updates the appropriate registers of the MAX17065.
A status bar is also provided at the bottom of the pro-
gram’s main window and is used to verify command
module and device connectivity. A Device Search
option is located in the Action menu bar should the user
want to switch from Demo Mode to normal operation.
Frequency Selection
The MAX17065 can be operated at either 0.6MHz or
1.2MHz. To set the desired frequency, select the
appropriate radio button in the Frequency group box.
The default frequency setting is 0.6MHz, but the EV kit
is designed for 1.2MHz. Component changes are
required when selecting different frequencies. Refer to
the MAX17065 IC data sheet for more information
regarding frequency selection.
Operating Mode
The MAX17065 can be operated in either Skip Mode or
Forced PWM. To set the desired operating mode,
select the appropriate radio button in the Mode group
box. The default operating mode is Forced PWM. Refer
to the MAX17065 IC data sheet for more information
regarding modes of operation.
ON Enables and Test
The ON2 and ON1 bits enable/disable the various out-
puts of the MAX17065, according to Table 1. To set
either bit high, check the respective ON_ checkbox in
the ON Enables group box.
Setting TEST1 and TEST0 checkboxes prevents the
VL, VH, VP, and VN outputs. In this mode, the output
can be driven by external voltage sources. Setting
either TEST_ bit to 1 in the Test group box disables the
discharge function. Refer to the MAX17065 IC data
sheet for more information regarding the test bits.
Fault Detection
The MAX17065’s Faults read-only register monitors the
OLED controller’s operating state, output, and thermal
faults. When a fault is detected, the corresponding bit is
changed from logic 0 to logic 1 and the font color is
changed to red. Refer to the MAX17065 IC data sheet
for more information regarding the Faults register.
Outputs
The MAX17065 allows for software control of the
charge-pump and negative SMPS outputs. Select the
appropriate voltages from the VL:, VH:, and VN: drop-
down lists to set the desired voltages. The default set-
tings are VL: -0.5V, VH: +5.5V, and VN: -0.5V.
Current Limit
The MAX17065 software allows the user to set cur-
rent limits for the negative and positive switching
power supplies. To set the current limits, select the
desired current limit from the IMAXN: and IMAXP:
drop-down lists in the Current Limit group box. The
default current-limit settings are IMAXN: 0.45A and
IMAXP: 0.45A.
Manufacturer ID/Silicon
Revision Detection
The ID Register group box shows the manufacturer ID
and silicon revision information of the MAX17065 IC.
This information is read upon initial start-up.

Simple I2C/SMBus Commands
There are two methods for communicating with the
MAX17065: through the normal user-interface panel
(Figure 2) or through the I2C/SMBus commands, avail-
able by selecting the Interface Diagnostic Window
menu item from the Action menu bar. The Maxim
Command Module Interface window pops up and
includes a 2-wire interface tab that allows for execu-
tion of simple I2C/SMBus commands.
The SMBus dialog boxes accept numeric data in bina-
ry, decimal, or hexadecimal. Hexadecimal numbers
should be prefixed by $ or 0x. Binary numbers must be
exactly eight digits. See Figure 3 for an illustration
of this tool.
Detailed Description of Hardware
The MAX17065 evaluation kit (EV kit) is a fully assem-
bled and tested surface-mount PCB that evaluates the
high-efficiency MAX17065 organic LED (OLED) driver.
The MAX17065 EV kit provides an on-board I2C/SMBus
interface and is connected to the computer through the
USB port. The EV kit includes Windows 2000/XP- and
Windows Vista-compatible software that provides a GUI
for control of the MAX17065’s output voltages, switch-
ing frequency, operating mode, current limit, and SMPS
and charge-pump enables. The MAX17065 EV kit oper-
ates from a +2.3V to +4.5V single power supply.
The MAX17065 includes dual SMPS outputs (+5.35
fixed positive and -5V to -0.5V adjustable negative),
one LDO (+1.9V/60mA), and dual regulated charge
pumps (+5.5V to +9V positive and -5V to -0.5V nega-
tive) for an OLED panel.
Shutdown Control
The MAX7065 can be placed in shutdown mode
through jumper JU1 (see Table 2). When connected to
GND or left open, the VD output is enabled with four ris-
ing CLK edges. When connected to VDDIO, the
MAX17065’s VD is enabled without a CLK signal.
User-Supplied VDDIO Input
The MAX17065’s VDDIO supply is powered from the
USB port by default. Move the shunt of JU2 to the 2-3
position to apply your own +1.6V to +3.6V power sup-
ply at the VDDIO pad. See Table 3 for jumper JU2 con-
figuration. VDDIO voltage decides the SHDN and CLK
logic levels. When CLK is driven by an external signal,
jumper JU2 can be placed in a 2-3 position to allow
external VDDIO voltage.
User-Supplied I
2
C/SMBus Interface
To use the MAX17065 EV kit with a user-supplied
I2C/SMBus interface, first move the shunts of JU5 and
JU6 to the 2-3 position. Then connect your SDA and
SCL signals to the corresponding SDA and SCL pads
on the MAX17065 EV kit board. Note: The I2C/SMBus
interface is not available until VD is enabled by either
SHDN = VDDIO or four rising CLK edges because SDA
and SCL are pulled up by internal 10kΩresistors.
