mately 5V by probing the D1 test point.

19) Set the DC power supply output to be less than 6V.

13) By default, the GUI is set for DO High-Side Mode. In

the System tab of the GUI, select the desired output

mode (High-side, High-side 2x Inrush Current, Ac-

tive Clamp Push-pull or Simple Push-pull) and select

On to set D_ logic input high, thus the corresponding

DOI_ output is enabled/turned on. Notice that the cor-

responding status LED (SLED_) lights up.

mately 0V by probing the D1 test point.

21) Repeat steps 17 to 20 to verify other DOI_ input be-

havior.

Detailed Description of Hardware

The MAX14906 EV kit allows the user to evaluate all

features and operational modes of the MAX14906, four-

channel digital-output, digital-input device.

14) Select Oﬀ in the pulldown menu to set the D_ logic in-

put low to turn oﬀ the corresponding DOI_ output. Verify

that the SLED_ is turned oﬀ, which indicates that the

15) Repeat steps 13 and 14 to verify other DOI_ outputs

and check that the status LED (SLED_) follows the

input setting.

The EV kit is powered from a single power supply and

accepts a wide range of supply voltages, from 10V to 40V

DC. The power is applied through two banana jacks, VDD

(+) and GND (-).

16) In the System tab select DI Mode for all DOI_ chan-

nels in the pulldown menu in the ﬁrst column. This

conﬁgures the DOI1 to DOI4 channels to Type 1 and

3 digital-input mode (DI mode) and sets D1 to D4 log-

ic pins to logic outputs.

The MAX14906 requires a 5V DC power supply on V . It

the SetOUT register (0x00). All the DOI_ channels can be

configured as either Type 1 and 3 or Type 2 digital inputs.

However, it is not possible to mix input types as the inter-

nal current sink is globally set to either 2.3mA (typ) for

Type 1 and 3, or 7mA (typ) for Type 2 inputs. By default,

the Typ2Di bit is set to 0, which is the Type 1 and 3 con-

figuration. The DOI_ inputs support a minimum operating

range of -3V to +30V which is compliant with IEC 61131-2

digital inputs standard. Input voltage can be applied to the

J12 terminal block or the DOI_ test points.

It can be powered by the internal 5V linear regulator when

the J7 header is left open and J5 is in the 1–2 position. If

a different logic level other than 5V is desired, for example

3.3V, an external power supply is needed to power up the

V pin through the V test point with a supply range of 2.5V

Power-Up Sequencing

1) Enable the +24V DC power supply.

2) Connect the USB A-to-micro-B cable from a PC to

the EV kit board.

3) Start the EV kit software.

When the GUI is not open, the DOI_ outputs are high due

to the D_ inputs being high since the device is in high-side

DO mode by default. When the GUI is open, the software

pulls D_ inputs low and then DOI_ outputs are also low.

Isolation Domains

The MAX14906 EV kit features galvanic isolation for

the 4-wire SPI, SYNCH, FAULT, and READY signals

using the MAX14483 and the D_ logic inputs/outputs

(D1, D2, D3 and D4) using the MAX14937s, whose

bidirectional channels allow the D_ signals to be trans-

mitted in both directions on the same line. Refer to

the MAX14906 EV Kit Schematic. The isolated logic

domain is powered exclusively from the USB connector

J202. The digital isolators, MAX14483 (U4) and the

MAX14937 (U2 and U3) keep the USB ground separate

from the rest of the MAX14906 circuitry.

Digital Output Operation

In the Digital Output mode, the user can control the

D_ logic inputs or HighO_ bits to enable or disable the

DOI_ outputs. The specific DO mode, such as High-

side, High-side 2x Inrush Current, Simple Push-pull, and

Active Clamp Push-pull can be selected in the pulldown

menu in the System tab, or by selecting the desired

output mode by using DoMode_[1:0] bits in the ConfigDO

register (0x0D). D_ logic inputs can be controlled either by

the EV kit GUI or by an external source when D_ signals

are disconnected from the on-board microcontroller using

the corresponding switch (SW1) channels. The external

D_ input signals can be applied to the D1 to D4 test points

or to J13 connector.

Protective Earth (PE) is provided on the upper-left cor-

ner of the EV kit with a safety rated Y capacitor (C13)

between the field ground (GND) and PE.

External pMOS Transistors

The MAX14906 EV kit has an external pMOS transistor

for each channel to protect the MAX14906 against high

reverse current flow into the DOI_ pins in the DO modes

and supports up to 30V input voltages in DI modes.

When using the external pMOS transistors, ensure J8,

J9, J10 and J11 headers are open, and gate drive pins

G1 to G4 are enabled by setting the GDrvEn_ bits to 1 in

the OpnWrEn register (0x08). The external pMOS tran-

sistors are always off and G1 to G4 pins are shorted to

Surge and ESD Protection

The MAX14906 EV kit is immune to ±1kV surge pulses

(1.2/50µs, according to IEC 61000-4-5) applied between

the DIO_ and field ground. Without external protection

devices, the DOI_ channels of the MAX14906 are pro-

tected against negative 1kV surges per IEC 61000-4-5

(42Ω/0.5µF). To protect the MAX14906 from positive

surge transients on the DOI_ pins, a suppressor/TVS

The EV kit drives outputs once On is selected in the

Register Settings Tab

Communicating with the MAX14906

The Register Settings tab allows full configuration of the

device, as shown in Figure 3. The full register map of the

MAX14906 is located on the left-side of the tab, and the

bit-by-bit control and description table is located on the

right side. When the register is selected in the register

table, the detailed description of each bit is shown in the

bit description table. The bit value can be changed using

pulldown menus in the Setting cell for each bit individu-

ally in the bit description table. Both tables are synchro-

nized in that changes made in one table appear at both

tables. There are several write and read options available

through the corresponding control buttons located below

the bit description table.

The MAX14906 EV kit communicates to a PC through

a USB port. The on-board FT2232 controller is

communicating with all digital signals including SPI, D1

to D4, SYNCH, READY and FAULT, and is managed by

the EV kit GUI software on the PC. This is ideal for quick

evaluation and to explore the features and functions of

the MAX14906.

If the user prefers to use their own microcontroller or

FPGA and their own software, all digital signals including

SPI, D1 to D4 signals, SYNCH, READY and FAULT are

available through J13. If J13 is used, disconnect the on-

board FT2232 controller from the MAX14906 by opening

all switches on SW1.

When the Auto Write button is selected, any data typed

in, or selected through the Setting pulldown menu is

automatically written into the corresponding writable

register. The button renamed to Stop Auto Write and

auto write function can be canceled by clicking on this

button a second time.

Detailed Description of Software

The MAX14906 GUI provides access to all registers and

allows full configuration and control of the MAX14906.

There are two tabs available to control the EV kit. The

System tab provides quick and basic control of the DOI_

channels. The Register Settings tab provides per-chan-

nel and enhanced diagnostic configuration and allows full

control of the device.

The Read All button performs a read operation of all reg-

isters after each click.

When the fault conditions occur, they set the bit(s) in the

corresponding read-only registers 0x02 to 0x07. The fault

conditions should be carefully evaluated and removed

externally (over-/undervoltage, thermal overload, open-

wire, etc.). It is recommended to read the Interrupt (0x03)

and GlobalErr (0x07) registers first to identify what kind

of fault conditions are present, then read per-channel

diagnostic registers 0x02, 0x04 to 0x06 twice to make

sure that the condition is gone and to clear the interrupts.

System Tab

The System tab allows the DOI_ pins to be configured in

Digital Output mode by selecting the first pulldown menu

to DO Mode. The type of digital output mode can be con-

figured by selecting the second pulldown menu, including

High-side mode, High-side with 2x Inrush Current mode,

Active Clamp Push-pull mode and Simple Push-pull

J1 in the 1–2 position and put the CRCEN slider to the

enabled position. To disable the CRC, set jumper J1 in the

2–3 position and set the CRCEN slider to disabled. The

SYNCH slider allows manual synchronization of multiple

devices.

The Burst Write allows the GUI to write to registers 0x00

and 0x01 only in one SPI cycle, while the Burst Read

allows the GUI to read multiple consecutive registers 0x02

through 0x07 (DoiLevel, Interrupt, OvrLdChF, OpnWirChF,

ShtVDDChF, and GlobalErr registers) in one SPI cycle.

The user must match A0 and A1 jumper position (2–3

position by default) on the EV kit with the SPI address

selected from the Address pulldown menu, located below

the register map table. The default address is 00.

There are a MAX14906 I/O Pins box and a SDO

Diagnostic Result box below the buttons. The SDO

diagnostic faults are updated after each SPI read or write

operation. To enable or disable the CRC function on the

SPI interface, both software and hardware configurations
