Evaluation Board User Guide UG-263 One Technology Way • P.O. Box 9106 • Norwood, MA 02062-9106, U.S.A. • Tel: 781.329.4700 • Fax: 781.461.3113 • www.analog.com Evaluating the ADM1275 and ADM1276 FEATURES GENERAL DESCRIPTION Full functions support evaluation kit for the ADM1275 and the ADM1276 Supports LFCSP device package Populated and tested with 12 V, 60 A, 4.7 mF design Capable of evaluating high current designs for over 100 A Special NMOSFET footprint suits different packages Supports up to 3 sense resistors in parallel Supports up to 6 FETs in parallel LED indicated status outputs Wild input voltage range of up to 20 V Allows separate VCC and VIN for low voltage sensing 6 on-board ADT75 accurate temperature sensors Supports cascade setup for multiple boards Toggle and push-button switch for easy input control PMBus communication support The EVAL-ADM127xEBZ is a compact full feature evaluation board for the ADM1275-1ACPZ, ADM1275-3ACPZ, and ADM1276-3ACPZ devices. The elaborated layout gives users a clear visual of all the peripheral components and the hot-swap power path. The layout also maximizes the board’s ability to dissipate heat for some of the key components on the power path, allowing the evaluation of very high current hot-swap setups. PACKAGE CONTENTS EVAL-ADM127xEBZ evaluation boards 8-way, 150 mm Micro-MaTch ribbon cable Device samples HARDWARE REQUIREMENT USB-to-I²C dongle USB-SMBUS-CABLEZ (USB-SMBUSCABLEZ is not included in the evaluation kit and should be ordered separately. Only one dongle is required in multiboard cascade setup.) SOFTWARE REQUIREMENT Analog Devices, Inc., hot-swap and power monitoring evaluation software Three sense-resistor slots and six 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. Six LEDs give users direct visual indication on variations in the board status, such as supply input, output, IC power good output, latch output, and GPO outputs. Six ADT75 digital temperature sensors on the back of the board allow users to obtain the board’s thermal data through an I2C bus in real time. The kit supports I2C communication, allowing users to communicate with the ADM1275/ADM1276 and the ADT75. The evaluation kit also supports cascade setup so multiple evaluation boards can be connected together and share the same I2C bus. The boards are fully compatible with the ADM1275/ADM1276 evaluation software tool, which can be downloaded at: www.analog.com/hotswap_powermonitor. Note that users may need the USB-to-I2C dongle, USB-SMBUSCABLEZ, to use the evaluation software tools. The standard evaluation kit is prepopulated and tested with a 12 V, 60 A hot-swap design capable of working with a 4.7 mF output capacitor. Complete specifications for the ADM1275 and the ADM1276 are available in the ADM1275 and the ADM1276 data sheets available from Analog Devices and should be consulted in conjunction with this user guide when using the evaluation boards.

Recommended Sense Resistor Footprint For the best current sensing accuracy with the footprint shown in Figure 3, chip resistors without a nickel barrier layer (usually in green color) 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. Alternative resistors should be tested independently. It is the responsibility of the user to ensure the layout dimensions and structure of the footprint comply with individual SMT manufacturing requirements. Analog Devices does not accept responsibility for any issues that may arise as a result of using this footprint. Rev.
