Four sense-resistor slots and six multipackage FET slots provide great flexibility and allow a wide range of application setups. PACKAGE CONTENTS EVAL-ADM1278EBZ evaluation board ADDITIONAL HARDWARE NEEDED Serial I/O interface USB-SDP-CABLEZ (not included in the evaluation kit and should be ordered separately) Only one dongle is required in multiple board cascade setup SOFTWARE NEEDED Analog Devices, Inc., hot swap and power monitoring evaluation software EVALUATION BOARD CONNECTION DIAGRAM Multiple test points allow easy access to all critical points/pins. Seven LEDs provide direct visual indication on variations in the board status, such as supply input, output, IC power-good output, fault output, current sense output, and general-purpose outputs (GPO). An AD7291 8-channel, I2C, 12-bit, successive approximation analog-to-digital converter (SAR ADC) allows users to measure voltages such as CSOUT and other pin voltages, as well as to read ambient board temperature through an I2C bus in real time. The kit supports I2C communication, allowing users to communicate with the ADM1278. 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 ADM1278 evaluation software tool, which can be downloaded from the ADM1278 product page. Users need a USB-SDP-CABLEZ USB-to-I2C dongle to use the evaluation software tools. POWER SUPPLY POSITIVE INPUT POWER SUPPLY NEGATIVE INPUT TEST POINTS The standard evaluation kit is prepopulated and tested with a 12 V, 73 A hot swap design capable of working with a 3 mF output capacitor. 11757-001 LEDs USB-SDP-CABLEZ SWITCH S1 Complete specifications for the ADM1278 are available in the ADM1278 data sheet, available from Analog Devices, which should be consulted in conjunction with this user guide when using the evaluation board.

Download the hot swap and power monitor software from www.analog.com/hotswaptools (see the UG-353 user guide for more information). Connect the evaluation board (EVAL-ADM1278EBZ) to a PC through the 10-way connector and USB-SDP-CABLEZ. Connect the power supply to the evaluation board (EVALADM1278EBZ) using thick wires suitable for the current levels to be observed. To confirm that the boards are configured correctly, set the output of the power supply to 12 V with less than 1 A current limit and with no load capacitance. If the boards are configured correctly, the green LED, labeled PWRGD on the EVAL-ADM1278EBZ, should illuminate. Push the ENABLE switch to the off position or press the push-button on the EVAL-ADM1278EBZ. The green LED, labeled PWRGD, should turn off and then turn back on again when re-enabled. 7. 8. 9. Rev. A | Page 3 of 18 If a fault event occurs (for example, a short circuit during operation), the red LED, labeled FAULT, illuminates. This fault can be cleared by toggling the ENABLE pin after the fault condition has been removed. Disable the hot swap using the Hot Swap Control section of the Basic Operation tab of the GUI. Disabling the hot swap turns off the green LED (PWRGD) on the evaluation board. Manually program the sense resistor value, if required, using the options in the GUI. Check that the voltage and current measurements are as expected (for example, VIN = 12 V) in the Power Monitor tab of the software GUI. UG-601 EVAL-ADM1278EBZ User Guide EVALUATION BOARD DESCRIPTION The board is intended to be plugged into a system where load capacitance already exists. Two through-hole vias are provided to allow the placement of a load capacitor on the board when testing the board outside of a real system. All testing performed on the board was done with a 3 mF load capacitor. The EVAL-ADM1278EBZ is designed to demonstrate several features of the ADM1278. A simplified drawing of the evaluation board is shown in Figure 2. The EVAL-ADM1278EBZ is connected to a PC using a USBSDP-CABLEZ dongle for I2C communication. The EVAL-ADM1278EBZ uses a 10 nF CTIMER1 capacitor to maintain a 1 ms FET safe operating area (SOA). The undervoltage and overvoltage thresholds were set using resistor dividers. A resistor divider was also used on the ISET pin to set the current limit to approximately 73 A. The constant power level was set to 180 W to allow the board to power up while maintaining the FET SOA at all times. These values can all be fine-tuned further if necessary. The EVAL-ADM1278EBZ is shown in Figure 1. To minimize inductance, use thick wires between the power supply and the EVAL-ADM1278EBZ board connector. The PWRGD, VIN, and VOUT LEDs illuminate green after the board is powered. 4.5V TO 20V RSENSE HS+ MO+ Q1 MO– HS– VCC VCAP GATE UV TEMP PWGIN OV VOUT ISET PSET ADM1278 PWRGD FAULT ISTART ENABLE GPO1/ALERT1/CONV GPO2/ALERT2 TIMER SCL SDA ADR1 ADR2 RETRY PGND GND Figure 2.

There is a resistor divider on the board to set the CSOUT within the input threshold range of the ADC, and another resistor divider is used to set it within the input threshold range of the comparator. When the CSOUT voltage exceeds the comparator threshold programmed by the AD5622 digital-toanalog converter (DAC) (via the evaluation software), an alert signal is asserted. The yellow LED (D2) illuminates to mimic this alert signal. The fast response time of the CSOUT pin to a load step (typically 10 μs) makes it suitable for fast alerts to overcurrent events. For example, it can be used to drive the fast PROCHOT pin of an Intel® processor for power throttling. 1 1 3 1 1 1 11757-003 2 DAC Figure 4. Multipackage N-MOSFET Footprint CSOUT 11757-022 ADC Figure 3. 11757-004 For the best current sensing accuracy with the footprint shown in Figure 5, chip resistors without a nickel barrier layer (usually green in 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. Figure 5. Recommended Sense Resistor Footprint BOARD SPECIFICATIONS Table 1.
