Description
System Featuring the LTM2987 Power System Manager The DC2023A is a demonstration system for the LT M®2987 16-channel I 2C/SMBus/PMBus power system manager with EEPROM. The LTM2987 monitors and controls 16 power supply rails. The DC2023A demonstrates the abil- ity of the LTM2987 to sequence, trim, margin, supervise, monitor, and log faults for 16 power supply rails. Each power supply channel’s output voltage is monitored and the LTM2987 monitors its own internal die temperature. The DC2023A is a single circuit board that contains sixteen independent power supply rails. The board employs sixteen LT C®3405A 300mA switch-mode regulators, which are configured to be controlled by the LTM2987. The LTM2987 is available in a µModule ® (micromodule) package and contains two LTC2977 devices. This board provides a sophisticated 16-channel digitally programmable power supply system. The rail voltages are programmable within the trim range shown in the Performance Summary. This demonstration system is supported by the L TpowerPlay™ graphical user interface (GUI) that enables complete control of all the features of the LTM2987. To- gether, the L TpowerPlay software and DC2023A hardware system create a powerful development environment for designing and testing LTM2987 configuration settings. These settings can be stored in the device’s internal EEPROM or in a file. This file can later be used to order pre-programmed devices or to program devices in a production environment. The software displays all of the configuration settings and real time measurements from the LTM2987. Telemetry allows easy access and decoding of the fault log created by the LTM2987. The board comes pre-programmed with the EEPROM values appropriate for the sixteen power supplies used on the DC2023A. Just plug and play! Multiple DC2023A board sets can be cascaded together to form a high channel count power supply (see Multi- Board Arrays). This cascaded configuration demonstrates features of the LTM2987 which enable timing and fault information to be shared across multiple ICs.

Larger arrays of LTM2987s are supported through programmable I2C base address or bus segmentation. The DC2023A demo board can be powered by an external power supply, such as a +12VDC supply. Communication with the software is provided through the DC1613 USB-to- I2C/SMBus/PMBus Controller.

Figure 3. DC2023A Top Side Details
The LTM2987 power manager on the DC2023A not only monitors each of the sixteen outputs but can margin the outputs either high or low. Margining is the operation that moves a rail either up or down for testing purposes. It allows a system to be fully characterized over supply limits without the use of external hardware or resources. The GUI provides an easy way to margin all rails high or all low by clicking one of four buttons. To invoke the margining dialog, click the GroupOp icon in the toolbar. The buttons labeled “ignore faults” will margin without creating a fault even if the fault limits are exceeded. common Demo BoarD operations A look at the telemetry window shows the effect of the margin high or margin low operation. The following screen shot shows all rails going from nominal set points to margin high, margin low, and back to nominal voltages. Each LTC2977 inside the module has a multiplexed ADC that is used to provide voltage, current, and temperature readback values. The telemetry plot in the GUI is similar to a multi-channel oscilloscope which is capable of displaying any parameter that is displayed in the telemetry window. Due to the nature of a multiplexed ADC converter, it has an associated ADC loop time. The total ADC loop time (~100ms to 160ms) for a given channel is dependent on the device’s configuration. Refer to the LTM2987 data sheet for complete ADC timing specifications. Creating a Fault There is a pushbutton on the DC2023A board that is used to force a fault and demonstrate the demo board’s ability to detect it and respond according to the configuration. When depressed, the pushbutton creates a fault on channel 10, the 2.5V output (GUI channel U1:2). The user should see all outputs power off, the fault LED momentarily illuminate, the alert LED illuminate continuously, and all rails sequence back on after a retry period. The user may also short any power supply output indefinitely. This is a good way to induce UV faults and shows that a shorted channel will not be damaged. Use a jumper wire or a coin to short any output.

aDvanceD Demo BoarD operations What Is a Fault Log? A fault log is a non-volatile record of the power system leading up to the time of fault. It holds the most recent monitored values (up-time, voltage, current, temperature) that can be analyzed to help determine the cause of the fault. It is a powerful diagnostic feature of the LTM2987 on the DC2023A demo board. Create a Fault and Fault Log To create a fault log, you must create a fault, as described in the Creating a Fault section. If multiple boards are configured, select the appropriate device in the system tree by clicking on the appropriate LTM2987 chip. We will proceed to work with the fault log. Working with the Fault Log Once a fault has occurred, the Fault Log (FL) icon will show a red (+) sign on it, indicating that the GUI has detected a fault log in the device. Clicking the icon will bring up a dialog box. Note that it is context sensitive. Be sure that the desired device is selected in the system tree. Notice that the checkbox “Log to EEPROM on Fault” is checked. Once a fault occurs, the device will automatically write the fault log data to EEPROM (NVM). At this point, the log is locked and will not change until it is cleared by the user. To read the EEPROM log data, first click the “NVM to RAM” button. At this point the RAM Log is locked and not updated even though the telemetry readings continue. Click the “Read RAM Log” button. The log data will appear in the text box below.
aDvanceD Demo BoarD operations The log contains timestamp, up-time, channel voltage readings, an input voltage reading, an on-chip temperature reading, etc. There will be a number of loops; each loop contains data obtained in one ADC loop time with the most recent ADC loop data on top and the oldest data at the bottom of the log. The up-time indicates, at the time of fault, the amount of time the device has been powered up or time since the previous reset. In this case, the fault log will show that channel U1:2 faulted due to a VOUT_UV_FAUL T condition. On the pre- vious telemetry loop, the channel voltage reading was a nominal value (2.5V). To clear the fault log, click the “Clear/Rearm EEPROM Log” button. This allows the selected device to be ready for a new fault event. To clear all faults, click the Clear Faults (CF) icon. Fault Sharing Setup in the GUI Fault sharing provides a means of propagating a fault de- tected by a power system manager to other power system managers via FAULT pins. Use the Fault Sharing Setup Tool to configure the fault sharing in the GUI. Select the LTM2987 labeled U0 in the system tree. Go to Utilities > Fault Sharing Diagram. For more details on this topic, please refer to the Fault Management section in the data sheet. The fault sharing dialog will appear as shown in Figure 10. All Response and all Propagate switches are closed by de- fault. In this configuration, a fault on one of the LTM2987 channels will shut down all 16 channels, and a fault on any LTM2987 channel will propagate to all channels on the DC2023A demo board since the fault pins are tied together. Note: All FAULT pins on the LTM2987 are tied together on the DC2023A demo board. These pins are open drain and have a common pull-up resistor to provide a logic high level (inactive). All FAULT pins are active low. There are two types of actions to fault conditions: How a channel responds to another channel’s fault and whether a particular channel propagates a fault to other channels. FAUL T pins are bidirectional, meaning the device may drive its FAUL T pin low (output) or may respond to the FAUL T
