Detailed Description of Software

Connecting to the MAX16031 EV Kit

Make sure the EV kit is connected to the PC by the USB

cable. Launch the software and in the Connect dialog

(Figure 1), select the I2C or JTAG radio button and

click OK. If the software is being used without the EV kit

connected, select the Demo (No Hardware Required)

radio button.

2

The I C slave address may be specified. The default is

0x18, but other values (depending on the settings of

jumpers J1 and J2) can be used.

Voltages Tab

The Voltages tab (Figure 2) provides a visual indication

of the voltage present on every IN_ input. Each channel

has a settings dialog (accessed by clicking the under-

lined IN_ link), a DAC output voltage setting, settings

for each overvoltage and undervoltage threshold, two

fault flags, and a chart-recorder view.

Figure 1. Connect Dialog

Figure 2. Voltages Tab

_______________________________________________________________________________________

3

MAX16031 Evaluation Kit

Each IN_ input can be connected to the on-board

MAXꢁ306 DAC using switch bank S1. This allows the

voltage at the IN_ input to be manually controlled through

the EV kit software. Click the link next to DAC Voltage to

set the voltage of the DAC in the 0 to 2.ꢁV range. The

DAC voltage can also be changed by dragging the dot-

ted green line, shown in the chart-recorder view.

To set the primary or secondary overvoltage or under-

voltage thresholds for a particular channel, click the

appropriate underlined number next to that parameter.

The primary thresholds can also be modified by drag-

ging the dotted red lines in the chart-recorder view. The

secondary thresholds can be changed the same way;

both appear as dotted yellow lines.

Two fault flag indicators are associated with each chan-

nel. The upper one corresponds to the primary fault

thresholds; the lower one corresponds with the sec-

ondary fault thresholds. If an undervoltage or overvolt-

age fault occurs, one or both these indicators will turn

red and remain so even after the original fault condition

is removed. To clear a fault indicator, click the indicator

and select Clear Fault or Clear All Faults on the menu

that appears.

Evluates:MAX6031

Each chart-recorder view shows the voltage on the cor-

responding IN_ input with a solid green line. To zoom in

and zoom out, click the magnifying glass icons in the

upper right of the chart-recorder view. Another way to

zoom in and out is to click and “drag” a selection rec-

tangle. Drag from upper left to lower right to zoom in,

and from lower right to upper left to zoom out.

Figure 3. Settings Dialog

The Settings dialog (Figure 3) can set the IN input-volt-

age range to one of three settings: 1.4V, 2.8V, and

ꢁ.6V. To enable channel monitoring, make sure the

Enable Fault Detection checkbox is selected. The

Disable Interrupts and Outputs for group box allows

faults on the primary or secondary thresholds to be

“masked,” which prevents them from triggering an

SMBus™ interrupt or asserting a fault output. The Save

State to EEPROM on group box selects which type of

fault can trigger a nonvolatile fault save operation.

Two IN inputs can be paired to form a combined differ-

ential input. Click any of the Single Ended links in the

center of the window to pair two inputs together, or to

separate two paired inputs.

the settings dialog. To enable channel monitoring,

make sure Enable Fault Detection is selected (Figure

ꢁ). The Disable Interrupts and Outputs for group box

allows faults on the primary or secondary thresholds to

be “masked,” which prevents them from triggering an

SMBus interrupt or asserting a fault output. The Save

State to EEPROM on group box controls whether a

fault can trigger a nonvolatile fault save operation.

Current and Temperature Tab

The Current and Temperature tab (Figure 4) provides

a set of chart-recorder views similar to the Voltages

tab. To select the display units for the temperature sen-

sors, click the appropriate setting of the Temperature

Display radio buttons.

Similar to the input channels on the Voltages tab, the

current and the temperature channels each have a set-

tings dialog. Click the title of each channel to display

Figure 4. Current and Temperature Tab

_______________________________________________________________________________________

5

MAX16031 Evaluation Kit

Each external temperature channel has some additional

items on the settings dialog, shown in Figure ꢁ.

Additional fault mask bits are provided for the diode-

short and diode-open faults, and two controls are pro-

vided to set the temperature offset and gain calibration

parameters. The value provided for gain controls the

current (in µA) of the internal high-current source, while

the offset controls the digital offset value added to the

temperature conversion result (in Celsius).

Output Control Tab

The Output Control tab (Figure 6) facilitates configura-

tion of the programmable outputs.

The MAX16031 has several programmable outputs:

FAULT1, FAULT2, OVERT, RESET, GPIO1, and GPIO2.

The FAULT1 and FAULT2 outputs can be configured to

depend on many combinations of fault conditions for all

voltage, current, and temperature channels that are not

masked. The OVERT output depends on combinations

of temperature-related faults. Finally, the RESET output

depends on a combination of fault conditions for both

voltage and temperature and for a programmable set of

voltage inputs. The RESET output also has a program-

mable timeout, which is the amount of time RESET

remains asserted after all fault conditions are cleared.

Evluates:MAX6031

GPIO1 and GPIO2 can be used as general-purpose

inputs or outputs (GPIOs), and can also be configured

to act as manual reset inputs or additional fault outputs.

When a GPIO is configured as a fault output, the follow-

ing fault conditions can be monitored:

•

Primary undervoltage and overvoltage for one

selectable voltage channel

•

One or more of the following: primary overvoltage

for all voltage inputs, secondary over/undervoltage

for all inputs, overtemperature for each sensor, or

secondary overcurrent

•

Both of the above options at once

Figure 6. Output Control Tab

Overcurrent settings include OC timeout, which con-

trols the amount of time a secondary overcurrent condi-

tion must be present before it triggers a fault, and OC

output pin, which controls whether the OVERC output

latches an overcurrent fault or follows the state of the

primary overcurrent comparator.

Miscellaneous Tab

Many other configuration options are available in the

Miscellaneous tab (Figure 7): the boot-up delay, the

temperature filter, overcurrent settings, deglitch set-

tings, fault settings, memory lock bits, and the SMBus

alert configuration.

Filtering of the voltage-monitoring channels is con-

trolled by the Hysteresis of all thresholds setting,

which sets the voltage difference between the rising

and falling voltage threshold of each fault comparator.

Require 2 faults in a row, when turned on, prevents

any voltage fault from occurring unless the fault condi-

tion is present for two complete ADC conversion cycles

in a row.

The After-boot timeout setting controls the time delay

from when power is applied, to when monitoring is

enabled. This can prevent a partially powered system

from triggering false fault signals during startup.

The Temp sense filter time constant provides the

ability to filter the temperature sensors to reduce noise.

_______________________________________________________________________________________

7

MAX16031 Evaluation Kit

The On major fault setting controls what information is

saved to the fault EEPROM during a fault condition.

Save only fault flags means that only the fault flags

are stored to EEPROM during a fault event; Save fault

flags and ADC means that both the fault flags and the

ADC readings for all channels are stored to EEPROM

during a fault event.

The registers and the configuration EEPROM can be

locked with the Configuration setting to prevent unin-

tentional modification of configuration settings. The lock

icon in the lower-left corner of the window also indi-

cates and controls this lock bit.

The fault EEPROM is locked automatically when a fault

condition occurs and must be unlocked before any

subsequent fault will get stored to EEPROM. Unlock it

using the ADC-related EEPROM lock setting.

Version code provides user access to register ꢁEh.

This register does not control any function of the chip,

but can be used to store user-defined data such as a

version number.

To enable full SMBus functionality and allow the

SMBALERT output to assert, the SMBALERT# Signal

option must be enabled.

Most configuration registers have a matching EEPROM

location that is copied to the register when the

MAX16031 powers up. The Registers tab places each

pair on the same row. After experimenting with a partic-

ular register configuration, that configuration can be

written to the EEPROM by clicking the Commit

Configuration to EEPROM button.

Registers Tab

Besides the easy-to-use GUI controls, the MAX16031

can also be configured by directly modifying the regis-

ters and EEPROM. The Registers tab (Figure 8) pro-

vides access to the registers and EEPROM. Modify a

register by clicking the cell under the Value column,

entering the new value, and pressing Enter or clicking

in another cell.

USB-Host Interface

Voltage Monitoring

The eight voltage monitoring inputs connect to pins on

P3 located on the left side of the board. Switch bank S1

allows each input to be connected to the output of a

DAC, which allows the voltage to be set using the EV kit

software for ease of evaluation. The DAC output voltage

range is limited to 2.ꢁV. Do not attempt to force an

external voltage while the DAC is connected; doing so

could damage the DAC or the external voltage source.

The MAX16031 EV kit includes a built-in USB-to-

2

JTAG/I C host interface. The host interface uses

Maxim’s MAX3420 USB peripheral controller, along

with a MAXQ2000 microcontroller to communicate with

2

the host PC and generate the I C/JTAG bus signals.

Three indicators (LED101, LED102, LED103) provide

status information of the host interface. LED101 lights

during EEPROM write operations, LED102 lights during

2

I C or JTAG bus activity, and LED103 lights when the

software is communicating to the EV kit.

Current Monitoring

The current-sense inputs are connected to pins on

header P3 and can be used in two ways. A small volt-

age source can be applied directly across CS+ and

CS-, which the MAX16031 will measure directly. For this

situation, J3 must be closed, which connects CS+ to

To facilitate prototype development and programming,

the host interface can be used to interface with a

MAX16031 on another board by turning off switches

1-7 in switch bank S2. This disconnects the on-board

2

MAX16031 from the JTAG and I C buses. Connect to

to ensure proper bias. As an alternative, a current-

sense resistor can be soldered in the R23 position and

CS+ and CS- can be connected in series with the

external circuit to be measured.

connector is shown in Tables 2 and 3. Note that the I C

pullup resistors are located on the EV kit.

The on-board MAX16031 can be connected to an

external JTAG or I C interface by turning switch bank

S3 (switches 1-7) off while keeping switch bank S2

(switches 1-7) on. Connect the external interface to P2

for JTAG or P1 for I C. The MAX16031 can be com-

pletely disconnected from the on-board USB host inter-

face by using this technique, while providing external

power to EXT PWR (J100 must be in the EXT position),

and disconnecting the on-board DACs by turning off all

the switches in switch bank S1.

If an external bias voltage is to be used, remove J3 and

connect the CS+ pin of P3 to the external source. Do

not supply a bias voltage higher than 28V. The current-

sense circuit in the MAX16031 will not function for bias

voltages less than 3V.

2

Temperature Monitoring

One of the temperature sensors is internal and the

other two are external. Both external temperature sen-

sors are included on the EV kit as Q1 and Q2, which

are diode-connected 2N3904 transistors. These can be

desoldered and replaced if necessary. The connec-

tions are easily accessible through header Pꢁ.

Each interface can be disconnected or connected sep-

2

arately. I C uses switches 1-3 on both S2 and S3 while

JTAG uses switches 4-7 on both S2 and S3.

Inputs and Outputs

Each output has a separate indicator LED and pullup

resistor, and each signal is brought out to a pin on P4.

An LED will light to indicate that the associated output

has gone to the logic-low state. The LEDs can be dis-

abled by turning off switch 8 in switch bank S2. The

pullup resistors are controlled by J4. To use an external

pullup voltage, connect J4 in the 2-3 position and con-

nect the voltage source to the VPU pin of P4.

Power Source

The MAX16031 IC can be powered from one of three

possible power supplies, controlled by jumper J100. To

power directly from the USB ꢁV supply, place the

jumper in the ꢁV position. To power from the on-board

3.3V regulator, place the jumper in the 3.3V position.

When the jumper is in the EXT position, the MAX16031

can be powered from an external power supply con-

nected to the EXT PWR test point. Do not supply a volt-

age higher than 14V.

GPIO1 and GPIO2 can also function as inputs. If they

are configured as such, connect the external input to

the GPIO1 or GPIO2 pin of P4.

Serial Interfaces

The MAX16031 has both a JTAG interface and an I C

A test point (REF) is provided to confirm the reference

voltage of the MAX16031, which is 1.4V (nominal). Do
