PACKAGE CONTENTS
EVAL-ADM1075EBZ evaluation board
HARDWARE REQUIREMENTS
USB-to-serial-I/O interface USB-SDP-CABLEZ (The USB-SDP-
CABLEZ is not supplied in the evaluation kit and should be
ordered separately from Analog Devices, Inc. Only one
USB-SDP-CABLEZ is required in the multiboard cascade
setup.)
8-way, 150 mm Micro-MaTch ribbon cable (optional)
SOFTWARE REQUIREMENT
Analog Devices hot-swap and power monitoring evaluation
software
GENERAL DESCRIPTION
The E VA L -ADM1075EBZ is a compact full feature evaluation
board for the ADM1075-1ACPZ and ADM1075-2ACPZ devices.
The layout gives users a clear visual of all the peripheral compo-
nents and the hot-swap power path. The layout also maximizes
the ability of the board to dissipate heat for some of the key
components on the power path, allowing evaluation of high
current hot-swap setups.
Three sense-resistor slots and three multipackage FET slots give
users great flexibility and allow them to simulate a wide range of
application setups.
Multiple test points allow easy access to all critical points/pins.
Seven LEDs give users a direct visual indication of variations in
the board status, such as system input voltage, isolation power,
IC
PWRGD
output,
LATCH
output, and GPO outputs. Three
ADT75 digital temperature sensors on the back of the board
allow users to obtain the FET temperature through an I
2
C bus
in real time.
The board supports I
2
C communication, allowing users to
communicate with the ADM1075 and the ADT75. A 64 Kb I
2
C
EEPROM is used to store the ADC resistor divider and sense
resistor values on board for use with the evaluation software.
The evaluation kit also supports cascade setup so that multiple
evaluation boards can be connected and share the same I
2
C bus.
The boards are fully compatible with the ADM1075 evaluation
software tool, which can be downloaded at
http://www.analog.com/hotswaptools.
Users need a USB-SDP-CABLEZ USB-to-I
2
C dongle to use the
evaluation software tools. A Micro-MaTch ribbon cable may also
be required if multiple evaluation boards are cascaded. This
cable can be ordered through Farnell.
The evaluation board is prepopulated and tested with a −48 V
(−36 V minimum to −75 V maximum), 10 A hot-swap design
with a 680 µF output capacitor. The part is configured to retry
seven times; however, the board is easily reconfigurable to select
different retry schemes (see Table 6).
Complete specifications for the ADM1075 can be found in the
ADM1075 data sheet available from Analog Devices and should
be consulted in conjunction with this user guide when using the
evaluation board.

EVALUATION BOARD DESCRIPTION
The evaluation board is designed to demonstrate many different
features of the ADM1075. Not all components are required in a
typical design. The functional block diagram in Figure 1 shows
the key components of the evaluation board.
The typical lab setup is shown in Figure 2. The hot-swap line input
voltage is connected across the RTN IN and −48V IN connectors.
A resistive load can be connected across RTN OUT and −48V
OU T. The mini-USB connector is used to supply 5 V power to the
isolated section of the board while the USB-SDP-CABLEZ is
connected to the 10-way connector, SK3, for isolated I
2
C
communication.
Isolation is required in most −48 V applications because there is a
large ground potential difference between the −48 V section of the
board and a PC or microcontroller. The ADuM1250 is used to
demonstrate I
2
C isolation on the board, and the ADuM3200 is used
to demonstrate isolation of other digital signals. The ADuM5404
provides quad-channel digital isolation with isoPower®. An
integrated dc-to-dc converter provides up to 500 mW of regulated,
isolated power from the isolated side to the −48 V side. When
the isolated section is powered, the isoPower is switched in to
power the 5 V components on the primary side of the board.

The ADM1075 can be powered via a shunt resistor from the hot-
swap line voltage or can be powered directly from a 9.2 V to 11.5 V
supply. The shunt power option is the default on the evaluation
board; however, an emitter follower can be reconfigured to generate
the chip voltage directly. The required board modifications are
shown in Table 1. More information on powering the ADM1075
can be found in the ADM1075 data sheet. The default power
configuration is shown in Figure 3, and the emitter follower
configuration is shown in Figure 4.

Figure 8. Recommended Sense Resistor Layout (Not on Rev. 0 Boards)
For the best current sensing accuracy with the footprint shown
in Figure 8, chip resistors without a nickel barrier layer (usually
in green) are recommended. The data in this user guide may
not be applicable to all resistors and results may vary depending
on resistor composition and size. Test alternative resistors
independently. It is the responsibility of the user to ensure that
the layout dimensions and structure of the footprint comply
with the individual SMT manufacturing requirements. Analog
Devices does not accept responsibility for any issues that may
arise because of using this footprint.

LIMITED TO, THE IMPLIED WARRANTY OF MERCHANTABILITY, TITLE, FITNESS FOR A PARTICULAR PURPOSE OR NONINFRINGEMENT OF INTELLECTUAL PROPERTY RIGHTS. IN NO EVENT WILL ADI AND ITS
LICENSORS BE LIABLE FOR ANY INCIDENTAL, SPECIAL, INDIRECT, OR CONSEQUENTIAL DAMAGES RESULTING FROM CUSTOMER’S POSSESSION OR USE OF THE EVALUATION BOARD, INCLUDING BUT NOT LIMITED
TO LOST PROFITS, DELAY COSTS, LABOR COSTS OR LOSS OF GOODWILL. ADI’S TOTAL LIABILITY FROM ANY AND ALL CAUSES SHALL BE LIMITED TO THE AMOUNT OF ONE HUNDRED US DOLLARS ($100.00).
