KIT34708VMEVBE
KIT34708VMEVBE is the evaluation board for the MC34708 Power Management
Integrated Circuit (PMIC), in a standalone environment. This board allows the user to
evaluate the MC34708 device under specific operating parameters through the use of a
dongle board and Graphical User Interface (GUI). A USB communication dongle board
is included to easily enable communication between a user’s PC and the MC34708
evaluation board. The GUI allows the user to program and control the power, battery
charger, ADC, coulomb counter, RTC, GPIOs, PWM, and USB features directly through
their PC. The board schematic and layout is Freescale’s recommended solution to
optimize the performance of the MC34708 PMIC.

This KIT is a USB communication dongle that uses the MC9S08JM8CLC MCU to
enable communication between a PC/laptop with a USB port, and the
KIT34708VMEVBE, through SPI or I
Beside communication, this board also provides two pins for quick “plug in”
identification, as well as three GPIOs, four PWM signals, and two ADC. All of these pins
can be configured and used as general purpose I/O pins, supplying a total of 11 GPIOs,
if needed.
The charge path can be configured for single or serial path using jumpers J2 and J4 to
enable/disable the M3 transistor. The PMIC charger can be supplied from:
Two LEDs are provided on the board to verify the charging status of the Li-Ion battery
attached to the board. When the red LED D1 is fully on, it is an indication that the
charging is still in progress; when blinking, it is an indication of a charging fault. When
the green LED D2 is lit, it is an indication that the charge is complete.
