Application Note 1654
CHARGE CURRENT
The Write Charge Current button sends only the charge current to
the ISL9519C. Other registers are unchanged,
The white text field on the left side of the Charge Current area
accepts input in amps and converts it to a hexadecimal (hex)
value to be written to the ISL9519C. This hex value is displayed in
the gray read-out window on the right side.
The hex value depends on the value entered in the Sense R in
mOhms text field on the far left of the Charge Current area.
The value in the white text field is forced to the nearest valid
number that can be produced by the DAC in the ISL9519C. For
example, if you enter 4 in the white text field and press Enter on
your keyboard, the gray read-out field changes to 3.968. If you
enter 4.1, the display changes to 4.096. The value entered can
be incremented and decremented with the up/down arrows to
the left of the white text field.
Values entered in the Sense R in mOhms text input fields on the
far left of the Charge Current and Input Current areas are used to
calculate the hexadecimal (hex) values and the SMBus
sequences for the Charge Current limit and Input Current limit
values entered in the white text input fields. The evaluation board
is built with 20mΩ/10mΩ sense resistors. If you change them to
another value, enter the new value to get correct calculations.
After entering a number in the Sense R in mOhms text input
field, press Enter or click in another area to enter the value. The
resulting hex value and SMBus sequence are calculated and
displayed in the gray SMBus SEQUENCE FOR WRITING REGISTER
(XX) read-out field for the register being programmed.
In this field, S = Start condition, A = Acknowledge, and P = Stop
condition. The LO byte is sent first and then the HI byte. For
example, when writing 0x41A0, 0xA0 is written first and then 0x41
is sent.
IMPORTANT NOTE: The SMBus commands are not sent until one
of the WRITE buttons is clicked (i.e., Write All or Write Charge
Current) (Figure 10).
MAX AND MIN SYSTEM VOLTAGE
IMPORTANT NOTE: Max System Voltage Commands that are
much higher than the voltage for the number of cells selected by
the CELL pin are ignored (not acknowledged). See the “Max
Accepted Max System Voltage Command” section of the
ISL9519C datasheet for details.
In the MaxSystemVoltage area of the DAC Controls tab, the Write
MaxSystem Voltage button writes only the MaxSystem Voltage
register. Other registers are unchanged.
The white text input field on the left side of this area accepts max
system voltage values in Volts and calculates the hexadecimal
value and the SMBus sequence to write to the ISL9519C. The
SMBus command is sent when the Write MaxSystemVoltage or
Write All button is clicked (Figures 11 and 12).
INPUT CURRENT
In the Input Current area of the DAC Controls tab, the Write Input
Current button writes only the Input Current register. Other
registers are unchanged. The white text input field on the left
side of the area accepts input current limit values in amps and
calculates the hexadecimal value and the SMBus sequence to be
written to the ISL9519C. The Sense R in mOhms text input field
on the far left of the area accepts input that is used to calculate
the hexadecimal value and the SMBus sequence. The SMBus
command is sent when the Write Input Current or Write All
button is clicked (Figure 13).
The ISL9519C shuts down unless it receives MaxSystem Voltage
or Charge Current commands every 175s. This is a safety feature
that prevents overcharging of batteries if the bus master has
stopped functioning. A toggle switch on the upper left of the DAC
Controls tab can be set to tell the software to write all commands
every 60 seconds.

User Interface Controls and Display
Information - Controls Bits Tab
The Control Register is modified in the control BITs tab by clicking
the toggle switches to change the control bit settings (Figure 14).
A selected bit is indicated by a raised green switch lever. The bit
pattern that is written to Register 3D is displayed in the gray
SMBus SEQUENCE FOR WRITING REGISTER 3D read-out field.
Click the Write CONTROL REG button to write the indicated
pattern. Click the READ ALL button to display the contents of
Register 3D in the gray read-out field. The functions of
Register 3D are described in the ISL9519C datasheet.
The READ ERROR or WRITE ERROR indicator flashes red if a read
error or write error, respectively, occurs. If this happens, check
the interface cabling. If problems persist, disconnect and reinsert
the USB cable, and click the RESET INTERFACE button.

Interface Troubleshooting
When the evaluation board is connected to the PC by a USB cable
and is communicating to the board through the USB interface, a
green check mark appears next to USB Interface Status in the
lower right corner of user interface window.
If there is a red X instead of the green check mark, it indicates a
problem with communication between the PC and the
microcontroller on the evaluation board. Check and correct the
connection of the USB cable to your PC and the evaluation board,
7
and then click RESET INTERFACE. If you still get a red X, close
and restart the ISL9519 control software.
If you still get a red X, with the ISL9519CEVAL1Z evaluation
board still connected to your USB port, open the Windows Device
Manager (Start->Control Panel->System->Hardware->Device
Manager). In the list of devices that appears, you should see a
device called NI-VISA USB Device. If it is not in the list of devices,
the driver may not be correctly installed. Run the New Hardware
Wizard as described in “Driver Installation” on page 2.
If you still get a red X, contact an Intersil Field Application
Engineer for assistance.
