DEVICE OVERVIEW

The ADM106x is a range of fully programmable supply

sequencers and supervisors which can be used as complete

supply management solutions in systems with multiple voltage

supplies.

All of the features of the ADM106x devices are programmable

through an SMBus interface. The devices also contain

nonvolatile memory (EEPROM) so the configuration of these

features can be stored on-chip and downloaded each time on

power-up.

CONTENTS OF KIT

• Main Evaluation Board:

This board contains all of the circuitry necessary to active

stimulate the ADM1062-69 devices and monitor its

response, such as programmable supplies, ADCs, LEDs,

etc.

• Daughter-card Socket:

A relevant daughter-card with a device socket is also

supplied. There are three different daughter-card options

for the main evaluation board depending on the package

option- LFCSP, TQFP or LQFP. The daughter-card plugs

directly into the main evaluation board and allows all the

devices in their specific layouts to be used in conjunction

with the main evaluation board. The correct one will be

supplied for the devices included in the kit.

• Device Samples:

Some loose samples of the device to be evaluated are

included in a samples box. A single device should be

placed in the socket before powering up the evaluation

board.

• SMBus Cable:

This cable connects the main evaluation board to a

standard PC parallel connector. Power must be applied to

the board separately if using this cable.

• USB Cable:

This cable connects the main evaluation board to a

standard PC USB port. Power for the evaluation board will

also be provided by the PC USB interface.

Order codes for evaluation kits are shown on this table (Pinouts

Preliminary Technical Data EVAL-ADM106x ADM106X CONFIGURATION TOOL INTRODUCTION The ADM106x Configuration Tool provided by Analog Devices enables the user to program the many features of these Super Sequencers through an intuitive, GUI based interface. The Eval board then allows the user to verify their configuration before using the ADM106x in their own system application. All of the circuitry provided on the board extra to the ADM106x can also be controlled using the same software provided.

Preliminary Technical Data EVAL-ADM106x attempts to recall settings saved for one device when another device is currently selected. This is so because different devices do not all have the same properties or functionality. Therefore it is recommended to combine the device number in the name of each saved configuration file to aid in easy loading of configuration settings. Figure 26.

Preliminary Technical Data EVAL-ADM106x renamed to 5V_IN. All references to the VP1 pin in the software are then updated with the new name. However, pressing the ‘Reset Pin Names To Default Names’ Button will reset all pin names throughout the program to the names as shown in the data sheet. The pin name update window is shown in Figure 30 below:- Figure 31. Pin Names window- default pin names Figure 33.
PAGE 22
EVAL-ADM106x Preliminary Technical Data SELECTING A VOLTAGE RANGE The input pins of the ADM106x can monitor supplies over a wide range- from 0.573V to 14.4V. Not all inputs can monitor over this range- the GUI shows over what range a given input can detect faults. In order to maximize the resolution of the programmed threshold, each input has a number of ranges. These ranges overlap to ensure that any threshold can be programmed over the full range of an input.
PAGE 23
Preliminary Technical Data EVAL-ADM106x PROGRAMMING AN INPUT THRESHOLD The Under-voltage and over-voltage thresholds are programmed by simply typing the required value in the input box indicated below and pressing on the keyboard. Once the user has entered a value the software will snap to the closest value that the resolution of the ADM106x’s threshold DAC will allow. The target threshold is displayed in volts along with the values that the fault will assert and de-assert.

This is shown in the window below. THE VX PINS AS DIGITAL INPUTS VX1-5 have dual functionality. As analog inputs, they can be programmed as described above. The only difference to the VP/VH inputs is that there is only one range to be selected and offer a true high impedance input.
PAGE 25
Preliminary Technical Data EVAL-ADM106x FET Driver Normal operation PROGRAMMABLE DIRECT OUTPUTS (PDO) The ADM106x features ten PDOs (eight inputs in the case of ADM1068/9). These outputs can be used to control the turn-on/off of supplies. The outputs are highly configurable. They can be programmed to pull- up to a number of different options.
PAGE 26
EVAL-ADM106x Preliminary Technical Data fails to occur. The user can set a time limit on how long it can take for the End-of Step to occur. If the event does not happen, then the user can take the decision to take some remedial action (e.g.) if a supply fails to come into tolerance after 100ms, it is likely that there is a fault on that supply and the user may wish to shut all supplies down. 3.

EXPANDING THE SEQUENCE SCREEN In most applications the sequencing engine program will become long and complex. To view the program in full screen click the up/down arrow icon left of the ‘sequencing engine program’ title to expand/shrink the program window. See figure 52. latch can be enabled on an individual state basis.
PAGE 29
Preliminary Technical Data EVAL-ADM106x Once a state has been programmed, the user may wish to do a number of things with it:- State 1. Insert a State - Once clicked, a dialog box appears as shown in figure 55 informing the user that a blank state will be inserted after the highlighted state. Rename a State - The State names can be altered to make them more meaningful (e.g.) a state to check if a 3.3V supply is valid could be called CHK_3.3V.
PAGE 30
EVAL-ADM106x Preliminary Technical Data SEQUENCING ENGINE DEBUG MODE A Debug option is also available which allows the user to step through the Sequencing Engine program slowly to determine any potential problems. This is located just beneath the editing tools, labeled “Enter SE Debug Mode”. This mode is only available when using the evaluation board and is not enabled when working offline. When < Enter SE Debug Mode> is clicked the screen in figure 60 appears. Figure 59.

Preliminary Technical Data EVAL-ADM106x Attenuation factor depends on range selected in inputs window Check to enable input Figure 63. Readback Window Input Attenuation - Selecting ranges on the input channels was discussed in the INPUTS section. By changing the range, a different attenuation network is selected, thus scaling the input voltage by a different factor. The scaling is done so that the input can be compared to the an on- chip 1.2V reference.
PAGE 32
EVAL-ADM106x Preliminary Technical Data WARNINGS RANGE Max SFD voltage allowed The WARNINGS function is a wide OR gate which is available as an input to the Sequencing Engine and can be used as condition to move out of a State. The inputs to this OR gate are the status of the secondary voltage detectors on VP1-4/VH and the status of the ADC readings relative to their limit registers. 0.573V to 1.375V 1.25V to 3.0V 1.375V Max ADC Voltage allowed 2.048V 3.0V 4.468V 2.5V to 6.0V 6.0V 6.0V 6.
