Pin
Name
Comments
1
DVDD
1.8-V regulated output. DVDD supplies the internal digital circuits
2
NFAULT
Fault indication output
3
VIO
Power supply input for UART/SPI input/output pins
4
RX/MOSI
UART receiver input or SPI master out slave in
5
TX/MISO
UART transmitter output or SPI master in slave out
6
SCLK
SPI clock input
7
nCS
Active low chip select pin for SPI interface
8
nUART/SPI (SPI_RDY)
This pin is used as an input pin to select SPI or UART interface before device finishes
wakeup/reset initialization. If SPI mode is selected, SPI_RDY is used to inform the host when
read/write can be initiated or if wait time is needed
9
GND
Ground
10
COMLP
AC coupled bi-directional I/O pin for daisy chain (VIF) communication
11
COMLN
AC coupled bi-directional I/O pin for daisy chain (VIF) communication
12
COMHP
AC coupled bi-directional I/O pin for daisy chain (VIF) communication
13
COMHN
AC coupled bi-directional I/O pin for daisy chain (VIF) communication
14
CVDD
Dedicated 5-V supply used for the daisy chain communications
15
BAT
Battery supply Input
16
INH
Inhibit pin to control system voltage regulators

Host Interface
There are three different ways for the host to connect to the BQ79600EVM: using the USB2ANY interface
adaptor, the UART FTDI cable ( to communicate through UART only), or using the LAUNCHXL2-
TMS57012 microcontroller BoosterPack connector.
The 10-pin J4 - serial connector is used to connect the BQ79600EVM to a PC running the GUI or to a
host controller. Texas Instruments recommends using the USB2ANY interface adaptor which includes the
proper 10-pin cable.
