Using the evaluation board and its accompanying software, the ADM1060 can be interfaced to a personal computer running Windows TM 95/98/2000/NT/ME/XP, via the computer’s parallel printer port. The evaluation board allows all of the many input and output functions of the ADM1060 to be exercised without the need for external components. A number of external connections to the SMBus is provided so that an in- system ADM1060 can be programmed using the Evaluation Board. The software provided allows control and monitoring of the ADM1060’s internal registers as well as controlling the peripheral circuits on the evaluation board which are provided to stimulate the many functions of the ADM1060. THE ADM1060 The following gives a brief description of the ADM1060 and its different applications. Further information can be found in the data sheet for the device. GENERAL DESCRIPTION The ADM1060 is a programmable supervisory/sequencing device which offers a single chip solution for multiple power supply fault detection and sequencing in communications systems. In central office, servers and other infrastructure systems, there are multiple dc supplies which are used to power different sections of boards (eg) 3.3V Logic circuits, 5V logic circuits, DSP core and I/O circuits etc. There is usually a requirement that certain sections power up before others (eg) a DSP core to power up before the DSP I/O or vice versa. This is in order to avoid damage, miscommunication or latch- up. The ADM1060 facilitates this, providing supply fault detection and sequencing/ combinatorial logic for up to 7 independent supplies. All of the detectors can be programmed to detect undervoltage, overvoltage or out- of window (undervoltage OR overvoltage) conditions. Other inputs to the ADM1060 include a Watchdog Detector (WDI) and 4 General Purpose Inputs (GPIn). The ADM1060 features 9 Programmable Driver Outputs (PDO’s). All 9 outputs can be configured to be logic outputs, which can provide multiple functions for the end user. PDO’s 1- 4 have the added feature of being able to provide an internally charge pumped high voltage for use as the gate drive of an external N- Channel FET which could be placed in the path of one of the supplies being supervised. All of the inputs and outputs described above are controlled by the Programmable Logic Block Array. This is the logic core of the ADM1060. It is comprised of 9 macrocells, one for each PDO. Any/all of the inputs can be used as an input to these macrocells. The PLBA outputs control the PDO’s of the ADM1060 via delay blocks, where a delay of between 0 and 500ms can be programmed on the rising and/or the falling edge of the data. All of the functional capability described here is programmable through the industry standard 2 wire bus (SMBus) provided. REV.

A number of checks are performed at this stage. Firstly there is a check for a valid Parallel port base address. The range Includes 0x278, 0x2BC, 0x378 and 0x3BC. The result of the search is displayed at the bottom right hand corner of the Address Search Window. If no valid base address is found then the dialog box of Figure 21 will Appear. Secondly there is a check for a valid ADM1060 device address. There are only four possible addresses 00, 01, 10 and 11, dictated by the setting of Pin 1 (A0) and Pin 2 (A1) in hardware. If one or more addresses are found then the Address Search Window will display the addresses that may be selected for configuration. A feature of this software is that it will allow up to four short circuits on the VPn or VH inputs. For example, four unpowered external PSUs connected to the Evaluation board. The software will automatically detect which of the five inputs has a valid supply by individually applying 5V to each of the inputs and checking each of the four possible ADM1060 addresses for a response. If five short circuits are detected the dialog box of Figure 21 will appear. Thirdly there is a check to see if the evaluation board is present. If an evaluation board is not detected then the lower rectangular box in the middle of the Device Address Window will turn red and will read “Evaluation Board Absent”. Note. When using the three pin SMBus cable (Not supplied in the standard kit) with the Evaluation Board, the data inputs to the GPIs in the ‘Evaluation Board Configuration’ window will have no effect. Four different ADM1060 devices can be addressed at any one time, depending on the hardware state of address bits A0 and A1. The Address Search Window shows which of these addresses are currently detected. Figure 19. Address Search Window (one ADM1060 device present) –18– REV. PrE 05/03 PRELIMINARY TECHNICAL DATA Preliminary Technical Data EVAL-ADM1060 One ADM1060 detected Multiple ADM1060s detected The screenshot in Figure 19 should appear when the standard Evaluation Board is connected before the program is launched. The ADM1060 on the Evaluation Board has the address set to 00 and a tick will appear in the ‘Address 00 Present’ box by default. Figure 19 above indicates one ADM1060 device with the address 00 (A8) is present. Click OK when ready to proceed programming this device. If there are multiple ADM1060 devices detected on the bus then the user must decide which one they would like to program. Figure 20 below shows the Device Search Window when more than one device is detected on the bus. A particular ADM1060 can be selected by placing a tick in the relevent box and clicking OK. Note. The ADM1060 device address is hardwired on the Evaluation board to 00 (A8). For this reason, multiple ADM1060 Evaluation Boards cannot be connected together to simulate multiple ADM1060 devices on a bus. If multiple ADM1060 devices were detcted the user can return to the Address Search Window at any time by selecting Select Device Address on the main Menu Bar.

The window has a graphical representation of the EEPROM, Holding and Controlling Registers and gives the user a greater understanding of the functionality of this block. The device address currently being configured is also displayed in this window. All the items that are green are control functions. There are four buttons and one drop down list box with further EEPROM options. Immediate Configuration Disabled/Enabled In Enabled mode (see Figure 27) the Holding Registers and the Controlling Registers are written to simultaneously therefore data written to the ADM1060 device over the SMBus interface will update the device immediately. On start-up this button defaults to Enabled. There is a switch icon in the data path to graphically show the function of this button. Note: In this mode Update Configuration button is unavailable. In Disabled mode (see Figure 26) data is written to the Holding Registers only. Therefore any changes to the configuration of the device will have no effect until the data in the Holding Registers is copied into the Controlling Figure 26.

Update Configuration Once the Update Configuration button is pressed the data in the Holding registers is copied into the Controlling Registers. There is a red progress line that shows the data is being copied. This button self clears (Resets) on completion of the task. Note: In this mode Update Configuration button is available. Download Configuration from EEPROM Once this button is pressed the data held in EEPROM is written to the holding registers. However, there are two points to note:1. If the Immediate Configuration is Enabled, the Holding registers become transparent and the data from the EEPROM is written to the Configuration Registers simultaneously. This is represented by a red progress line that shows the data is being written to the Holding and Controlling registers. 2. If the Immediate Configuration is Disabled, the data from EEPROM is written to the Holding registers first then it is copied to the Configuration registers. This is represented by a red progress line that shows data is being written to the Holding registers and then to the Controlling registers with a delay. This button self clears (Resets) on completion of the task. Copy Configuration to EEPROM Once this button is pressed the contents of the Controlling registers are copied into EEPROM. This is represented by a red progress line that shows data is being copied to the EEPROM (see Figure 30). This button self clears (Resets) on completion of the task. Figure 29.

PrE 05/03 PRELIMINARY TECHNICAL DATA Preliminary Technical Data EVAL-ADM1060 Configure User EERPOM The window in Figure 31b is for the configuration of the user EEPROM. Upon opening the window the 32 locations of page 1 in the user EEPROM are read and the values are displayed in the red boxes. These red boxes are also for the user to enter an 8-bit Hex word. This is achieved by highlighting the value displayed in the box, then enter a new value. Once a value is highlighted it is possible to Tab through the input fields. To the left of each of these red boxes is the location in EEPROM the input values live. If the value entered in the boxes exceeds FF the software will snap the value back to the highest allowable value. There are 8 different pages that the user may use. It is important to note that the software will automatically write data to EEPROM every time the page is changed. This prevents loss of data if the user were to change page without first pressing the button at the base of the window to write data to EEPROM. However, it is good working practice to press this button each time the user configures the page. Note: When the page is changed or the Press To Write Data button is pressed DO NOT attempt to change page. The program is performing a read and write operation and the user must wait until the Page button or Press To Write Data button resets itself before continuing. Figure 32a.

Again, resolution to 1 LSB is provided by using the up/down arrows at either end of the slide:- Figure 37. Selecting Fault Type Setting the Glitch Filter Each of the SFD’s has a programmable glitch filter which enables the user to ignore the output of the SFD for up to 100␮s. This is useful for preventing the ADM1060 from changing the system setup based on transient noise in a supply. The time length of the glitch filter is, again, selected in a dropdown menu (see below):- Figure 35.

PROGRAMMABLE LOGIC BLOCK WINDOW Each of these inputs can be inverted or uninverted by clicking The logical core of the ADM1060 is the Programmable Logic Block Array. This is comprised of 9 macrocells or Programmable Logic Blocks (PLB’s), one for each PDO. Here the user can program the device to control the status of the PDO’s based on the logical status of the SFD’s the GPI’s, the WDI and the other PLB’s (a PLB cannot be input to itself).

The delay can be placed on the rising edge and falling edge independently. The PDB timeout is programmed in the window shown:- The logic output of each PDB can be inverted/non-inverted using the following buttons :- PROGRAMMABLE DRIVER OUTPUTS WINDOW Figure 44. PDB Adjust Block There are 9 Programmable Driver Outputs (PDO’s) on the ADM1060. These can be used as POWER_GOOD, RESET, LDO Enable, or in the case of PDO’s 1 to 4, as a high voltage (~11.5V) for the gate of an external FET. The PDO’s can all be configured in the window inside the red border at the bottom of the PLBA window. Selecting Data Input Type The data driven onto the PDO can come from 3 different sources:PLB Data- the output of the Programmable Logic Block associated with a given PDO. SMBus Data- the PDO output can be driven directly from the SMBus, enabling a microprocessor or controller to directly control the state of the output. MCLK Data- the on board clock, used to generate the timeouts for the glitchfilters, PDB’s etc, can be routed out on the PDO pin and measured.

These functions may only be able to tolerate logic inputs at a level at or below their supply voltages. These supply voltages will be (most likely) supervised by the ADM1060 and available on- chip. Therefore, a feature has been provided where the external PDO’s can be pulled up to a number of these voltages on chip. Alternatively, the PDO can be pulled up to an external voltage, not available on- chip. There are a number of pullup options:- • • Weak Pullup to VH (up to a max. of 4.5V) Strong Pullup to VH (better ability to drive more capacitive loads). • • • Weak/strong Pullup to VPn Weak/strong Pullup to VDD Pullup to charge pumped high voltage (VFET- PDO’s 1 to 4 only) These options can be selected in the window as shown in Figure 47. Figure 47. Selecting PDO Pullup Option EVALUATION BOARD CONFIGURATION Once the ADM1060 configuration has been set up in the configuration registers, the Evaluation Board can be used to verify that the settings in the configuration registers are correct, by emulating an in- system environment. The following is provided to stimulate the many functions of the ADM1060 7 DAC’s to provide programmable (over the SMBus) supplies to the VH, VPn and VBn, thus enable testing of the Undervoltage and Overvoltage threshold and hysteresis settings in the configuration registers. All of the above functionality is configured in the Evaluation Board Setup Option under the Evaluation Board Configuration Menu (see Figure 48 below). Selecting the option starts up the Evaluation Board Configuration window. There are 3 submenus which the user can select to enable all of the functions on the Eval board which are external to the ADM1060 itself. Each of these submenus is described in detail. 9 ADC’s to measure and verify the voltage that each of the PDO’s has been pulled up to when asserted/de-asserted . 4 Pin Drivers to drive each of the GPI’s high and low. 1 On board programmable clock for verifying the Watchdog Detector functionality. 1 external LDO for verifying closed loop control of the ADM1060 over external devices.

These can be driven by RESET signals, Manual Reset, PWR_GOOD etc. In order to simulate logic signals being applied to these inputs, 4 data lines are provided from the PC parallel port, one for each GPI. These are assessible via the window shown in Figure 50. The user can set the logic level applied to the device by clicking on the relevant button, e.g. . The button will toggle from 1 to 0 (high to low) and vice versa, indicating the level being driven on the GPI. Each of the GPI’s can be connected/disconnected from the ADM1060 via software. This is done by clicking the relevant button. Opening these switches allows the user to connect their own external signal to a GPI (via J1). to GPI1 is provided in the GPI/LDO window. Clicking the switch symbol connects LDO-ERR and disconnects the PC data line. Note: LDO Switch and Data 1 Switch cannot be selected at the same time. The software will flag a warning if the user tries to do this. WDI WINDOW The ADM1060 features a Watchdog Detector circuit, WDI. This is used to monitor processor clocks and asserts if there is no transition on the clock within the programmed timeout period. In order to verify this function the ADM1060 Evaluation Board feature a programmable clock generator on board. The window in Figure 51 controls this clock generator. The period of this timer can be programmed by sliding the Timing Bar to the required timeout, as shown below. The timeout can be up to 16 seconds long (approx.). This programmable clock can be connected/disconnected to the ADM1060 in the same manner as GPI’s (ie) by clicking the button. Again, disconnecting this clock enables the user to apply an external clock to the WDI pin via the connector (J2). Figure 50.
