USB-to-I2C Interface Dongles
USB-SMBUS-CABLEZ, USB-5PSMBUS-CABLEZ
GENERAL DESCRIPTION
This data sheet provides details of the USB-to-I2C® interface
dongles. The USB-SMBUS-CABLEZ is a 3-pin version designed
for use with the ADM1062/ADM1063/ADM1064/ADM1065/
ADM1066/ADM1067/ADM1068/ADM1069 (hereafter referred
to as ADM1062 to ADM1069) family of programmable super
sequencers. The USB-5PSMBUS-CABLEZ is a 5-pin version for
use with the ADM1175/ADM1176/ADM1177/ADM1178 family
of hot swap controllers and ADM1191x power monitoring devices.
then be used to access and program a supported I2C device
using the appropriate PC software. Note that a suitable power
supply must also be provided to the device.
Both dongles provide clock (SCL), data (SDA), and GND
signals. The USB-5PSMBUS-CABLEZ also provides a CONV
and an ALERT signal. The signals are labeled on the crimp
housing of the cable. It is advisable to mark Pin 1 of the header
on the board to ensure correct orientation upon connection, as
shown in Figure 1. Figure 2 shows the schematic for the PCB
contained in the USB port dongle. The schematic is the same for
the USB-SMBUS-CABLEZ and the USB-5PSMBUS-CABLEZ.
The dongles are designed to connect a standard PC or notebook
USB port to a 3-pin or 5-pin header on an evaluation board,
system board, or preprogramming module. The dongles can
