General Description
The MAX14916PMB (peripheral module board) provides
the hardware to evaluate the MAX14916 Octal 1A / Quad
2A industrial high-side switch with diagnostics. Refer to
the MAX14916 IC data sheet for detailed information on
the operation of the IC. The module takes advantage of
the features in the MAX14916, which allow each channel
to independently be toggled on and o󰀨 and continuously
monitored for faults. Note the module provides a
subset of the MAX14916 features. For greater flexibility,
refer to the MAX14916 evaluation kit.
The MAX14916PMB# has a 12-pin Pmod™-compatible
connector for serial peripheral interface (SPI) commu-
nication. The peripheral module can be used in various
ways; Analog Devices sells low-cost USB2PMB2#
and USB2GPIO# adapter boards that use the Munich
GUI software for SPI communication through a USB
cable. This is not included with this board but is availa-
ble from Analog Devices or one of its distributors.
Alternatively, use any microcontroller or field
programmable gate array (FPGA) with a 12-pin Pmod-
compatible connector for SPI communication.
The PCB dimension is 62mm long x 22.6mm wide, with
the width determined by the size of the DO terminal block.

8) Once the hardware is ready to use, launch the
Munich GUI software. The status bar in the GUI
should display Disconnected in the bottom right
corner. To congure the MAX14916PMB#, go to the
Device tab, select Industrial Digital, then select the
MAX14916PMB. (See Figure 3)
9) The GUI should automatically detect the USB-
2PMB2# board serial number and show it in the
USB2PMB Adapter dropdown menu. If no serial
number is displayed, check the USB connection,
and click Scan Adapters. Select the USB2PMB2#
board serial number from the dropdown menu once
it shows up.
10) Click Connect.
11) Connect CH1 (pin 7) and GND (pin 8) from the J3
connector to an oscilloscope or digital multimeter.
The MAX14916PMB# is congured in HighImped-
ance mode (High-Z) by default after power-up. Using
the CH1 dropdown menu, turn on CH1 by setting the
signal type from the default High-Z to Static High.
Observe that STATUS LED (DS2 - green) is turned
on and the output on the oscilloscope or digital multi-
meter reads 24V.
12) Observe that when the output channel is turned on
and is shorted to GND, the Status LED turns o󰀨
and the Fault LED (DS6 - red) toggles on and o󰀨 as
the output detects an overcurrent or overload fault.
The Munich GUI’s Channel Faults box indicates the
channel in fault condition by turning the correspond-
ing channel’s status bar to red.
13) Monitoring for open-wire detection (with channel
output ON and/or OFF) can be enabled in the Moni-
toring Setup Window of the Munich GUI. Channel
Output connected to VDD monitoring can also be en-
abled in the same window. When a fault is enabled
in this window and detected on the MAX14916PMB#
board, it displays in the Munich GUI’s SPI Result
Monitoring Window box and the fault LED for the
channel turns ON.

MAX14916PMB
Detailed Description of Hardware
The MAX14916 is a high-speed, Octal 1A / Quad 2A
High-Side Switch with a maximum of 250mΩ on resis-
tance. The MAX14916PMB# is configured to be operated
as a Quad 2A High-Side Switch. Each channel’s output
can be toggled independently, and the IC provides chan-
nel diagnostics through an SPI-compatible interface. The
MAX14916 is specified for operation with a field supply
voltage of 24V typical and tolerant to 65V. The
MAX14916PMB# comes with a standard 2.1mm barrel
connector as the main sup-ply connector. A 24V (2.71A
max) DC power adapter is included with the module for
convenience. For ease of use, this module only supports
a subset of the MAX14916 features. For greater
flexibility, refer to the MAX14916 evaluation kit.
The MAX14916PMB# hardware provides everything
needed to evaluate the MAX14916 using the Pmod inter-
face. An optional USB2PMB2# or USB2GPIO# adapter
can be used with the Munich GUI to provide the USB-to-
SPI interface to communicate with the MAX14916. The
adapter provides a 3.3V output from the USB interface
providing a VL supply to the MAX14916.
The MAX14916PMB# does not feature galvanic isolation.
To isolate the module, select the USB2GPIO# adapter
board and use it with the USB2GPIOISO# isolation mod-
ule. Both modules work seamlessly with the Munich GUI.
High-Side Switch Operation
The MAX14916 has eight high-side (HS) switch chan-
nels. The MAX14916PMB# connects two high-side switch
channels in parallel to provide four output channels with
a higher current delivery capability. The high-side switch
current limit is 2.4A per channel when configured in this
parallel orientation.
The high-side driver has 120mΩ (typ) on-resistance at
25ºC ambient temperature. For full details about the high-
side switch characteristics, refer to the MAX14916 IC data
sheet.

MAX14916PMB Evaluates: MAX14916
Pmod Style Connector
The MAX14916PMB# can plug directly into a Pmod-
compatible port through J1. Note the pin definitions are
determined by the USB2PMB2# or USB2GPIO# adapter,
and to use this board with own host, configure the micro-
controller or FPGA to match the MAX14916PMB# J1 pin-
out. For more information on the MAX14916 SPI interface
and control, refer to the MAX14916 IC data sheet. See the
MAX14916PMB schematic for the J1 pinout.
Power Supply
A 24V DC power adapter, SDI65-24-UDC-P5, with a
maximum of 2.71A output current is included with the
MAX14916PMB# and must be connected to J2 for normal
operation. For a higher total load current on the output
than the power adapter can provide, use own DC power
supply. Note the MAX14916 is specified for operation with
a supply voltage up to 36V and is tolerant to 65V. The
barrel connector J2 is rated up to 5A maximum. Do not
operate beyond these maximum ratings.
Light-Emitting Diodes (LEDs)
The MAX14916PMB# comes with a 4 x 2 LED matrix,
providing four green LEDs indicating per-channel input or
output status, and four red LEDs indicating per channel
fault conditions. See Table 1 for a full list of each chan-
nel’s corresponding status and fault LEDs. If a fault LED
is turned on for a channel, the corresponding status LED
is always turned off. This mitigates false information about
the status of the affected channel.
Field supply (VDD) diagnostic faults are provided through
the VDDOK LED (DS9 - green). The Munich GUI pro-
vides limited access to the diagnostic features of the
MAX14916. To explore the full diagnostic capabilities of
the MAX14916, refer to the MAX14916 evaluation kit.
Transient Immunity Protection
No external surge suppression is needed on OUT_ pins
as they are protected against ±1kV surge pulses per IEC
61000-4-5. Connect a TVS diode between VDD and GND
to clamp positive surge pulses on the OUT_ and VDD
pins. The MAX14916PMB# outputs are protected against
±1kV surge transients with TVS diode D1, SMBJ36A, con-
nected between VDD and GND.
Addressable SPI
Figure 5. Digital Output Operation Mode Configuration
The MAX14916 supports addressable SPI, allowing direct
communication with up to four MAX14916 devices. By
default, the MAX14916PMB# is configured as address
00, with A1 = 0 and A0 = 0. It is possible to change the
SPI address using the provided resistor footprints by con-
necting A1 and A0 to VL or GND using the pads provided
at R10 and R11. Note that if the SPI address is changed
from the default value, it no longer works with the pro-
vided Munich GUI software and the user must develop
own software to support the new SPI address. For more
information on SPI device address selection, refer to the
MAX14916 IC data sheet.

Detailed Description of Software
For easy development and testing, Analog Devices
provides the Munich GUI to communicate with the
MAX14916PMB#. The Munich GUI supports many
different Pmod boards using low-cost USB adapters,
USB2PMB2# or USB2GPIO#, also available from Analog
Devices.
Connection to Hardware
The Device menu has options to select peripheral mod-
ules (see Figure 3). In this case, select
Industrial Digital, then select the MAX14916PMB. Use
the Scan Adapters option to search for the USB2PMB2#
or USB2GPIO# modules connected to the PC if the GUI
does not automatically find the Pmod adapters. If the
adapters are found, the serial number of the adapters
are listed in the USB2PMB Adapter dropdown. Select
the serial number of the adapter for the Munich GUI to
communicate with. The software can only communicate
to one module at a time. Select Connect and notice how
the status changes from Disconnected to Connected in
the lower-right area of the GUI. The Short-VDD per chan-
nel monitoring is automatically enabled, and all Global
Faults are Low, if the Munich GUI successfully commu-
nicates with the MAX14916PMB# (see Figure 4).
Pulse Mode
Drive a pulse signal for each output channel and config-
ure its ON and OFF time by selecting Pulses (Ton/Toff)
from the dropdown menu, as shown in Figure 7. To con-
figure the ON and OFF time, first set up the Ton for each
channel, and then adjust Toff only for one channel. The
cycle is automatically equalized so that the pulse periods
on all channels configured in pulse mode are the same.
Different cycle lengths between different output channels
are not supported, and the total time (Ton + Toff) should
be less than 1000ms. Once the appropriate Ton and Toff
values are entered, click the Run button to activate the
pulse output.

MAX14916PMB Evaluates: MAX14916
High-Side Switch Operation
All channels of the MAX14916PMB# are configured in
High-Impedance mode by default after power up. The
CH1 to CH4 dropdown menus allow to configure all four
high-side switch channels. The output channels can be
driven to High-Z, Static High, or Pulses (Ton/Toff), as
shown in Figure 5. When configured to Static High, the
channel switch is turned on, and the CH_ output is pulled
to VDD. The pulse mode is discussed in the Pulse Mode
section.
Diagnostic Features
The MAX14916PMB# takes advantage of the built-in
diagnostic features of the MAX14916 and provides basic
fault monitoring using the Munich GUI. To explore the
full diagnostic capabilities of the MAX14916, refer to the
MAX14916 evaluation kit.
Six global faults are provided on SDO in each SPI cycle
and are displayed in the Monitoring section in the Munich
GUI, which include short-to-VDD (SHTVDD), open-wire
detection in on-state (OWOnF), open-wire detection in
off-state (OWOffF), overcurrent limit (OvrCurr), channel
overload (OvldF), and the global diagnostic (GLOBLF).
The global fault bit (GLOBLF) is the logical OR of the
ComErr, SupplyErr, and ThrmShutd bits in the Interrupt
and GlobalErr registers. Also enable or disable per-
channel open wire detection (OW CH1 to OW CH4) and
per-channel short-to-VDD monitoring (Short-VDD CH1
to Short-VDD CH4), as shown in Figure 6. Refer to the
MAX14916 IC data sheet for more details on the per-
channel and global diag-nostics features.
