Detailed Description of Hardware

The MAX14912PMB hardware provides everything needed

to evaluate the MAX14912 using the SPI serial interface,

and includes the MAX14912, a terminal for the 8

external loads, and a 24V DC power connector. An

optional USB2PMB2 module can be used with the Munich

GUI to provide the USB-to-MAX14912 interface to control

the MAX14912. The USB2PMB2# adapter provide a 3.3V

input from the USB interface providing VL to MAX14912.

Note an external 24V DC supply is required even if used

with the USB2PMB2# and a USB cable.

Pmod Style Connector

The MAX14912PMB# can plug directly into a Pmod-

compatible port through X1. Note the pin definitions are

SPI, and the user must configure the microcontroller or

FPGA to match MAX14912 signals. For more information

on the interface and control, refer to the MAX41912 IC

data sheet. See MAX14912PMB Schematic for the X1

pinout.

External Supply

An external 24V DC supply is required to be connected to

X2. The rating of this supply must be aligned to the load

connected to X3.

LEDs

The 4 x 4 LED driver crossbar matrix offers a pin-

optimized configuration for driving 16 LEDs. Per-channel

output status and the fault conditions are indicated by

individual LEDs, 8 Green LEDs for status and 8 Red LEDs

for faults. If a FAULT LED is turned on for an output, the

corresponding STATUS LED is always turned off. This

mitigates false information about the status of the affected

OUT_ pin.

External Loads

An output connector is provided for each output along

with a GROUND signal. See MAX14912PMB Schematic

for the X3 pinout.

#Denotes RoHS compliant.
