Evaluates: MAX14914 MAX14914 Peripheral Module General Description Features The MAX14914 peripheral module provides the hardware Easy Evaluation of the MAX14914 to evaluate the MAX14914 high-side/push-pull driver that Configurable as a Digital Input or a High-Side or operates as both an industrial digital output (DO) and an Push-Pull Digital Output industrial digital input (DI). Refer to the MAX14914 IC data Accurate Internal Current Limiter for Types 1, 2, and sheet for detailed information regarding operation of the IC. 3 Digital Inputs The module can be used in various ways Maxim sells a Support High-Side Current Up to 1.3A with External low-cost USB2PMB1 adapter board that uses the Munich 24V Supply GUI software for communication through a USB cable. Adjustable Short-Circuit Current Limit This is not included with this board. Alternatively, any TM microcontroller or FPGA with a 12-pin Pmod -compatible Safe-Demagnetization for Safe Turn Off of Unlimited connector can be used, but the user needs to adapt the Inductance signalling because this is not a standard SPI port. Another Works with USB2PMB1 Adapter and Munich GUI option for the user is to wire-wrap a temporary connection Software from their system to the pins on connector X1. Fully Assembled and Tested Contents Proven PCB Layout MAX14914PMB with the MAX14914 RoHS Compliant Ordering Information appears at end of data sheet.

Use the Scan Adapters option to search 24V DC supply (> 1.5A recommended) not included for the USB2PMB1 modules connected to the PC. If The following items are Optional: modules are found, the serial numbers of the modules are USB2PMB1 adapter board listed in the USB2PMB1s menu item. Select the serial Mini-USB cable number in the USB2PMB1s list to connect the software to communicate with that module. The software can only Windows XP, Windows 7, Windows 8.1, or communicate to one module at a time only. Windows 10 PC with a spare USB port Setting MAX14914 Configuration Note: In the following sections, software-related items are identified by bolding. Text in bold refers to items directly The Setting buttons (Figure 1) control the configuration from the EV system software. Text in bold and underline and operating modes for the MAX14914: refers to items from the Windows operating system. DI ENA defines the DOI as a digital output (set to 0) or as a digital input (set to 1). Procedure DO PP defines the mode of DOI, depending upon how If the USB2PMB1 adapter is used, the user can download DI ENA is set. If the MAX14914 is configured as a digital software by following the steps below to get started: output, DO PP selects high-side mode (set to 0) or push- 1) Visit www.maximintegrated.com/evkitsoftware to down- pull mode (set to 1). If the MAX14914 is configured as a load the latest version of the Munich GUI software, digital input, DO PP selects type 1/3 mode (set to 0) or version 2.12 or later, Munich GUISetupV2.12.ZIP. type 2 mode (set to 1). 2) Save the software to a temporary folder. Unzip the DO SET is used when the MAX14914 is configured as a .ZIP file and double-click the .EXE file to run the DO when DO SET is 0 the output pin DOI is either high installer. A message box asking Do you want to impedance (in high-side mode) or 0V (in push-pull mode). allow the following program to make changes to When DO SET is 1, the output pin DOI is turned on (24V) this computer might appear. If so, click Yes. 3) The installer includes the drivers for the hardware and in high-side mode or in push-pull mode. software. Follow the instructions on the installer and Changing one of these buttons causes changes to be once complete, click Finish. The default location of made directly to the MAX14914. the software is in the program files directory. 4) Connect the MAX14914PMB Pmod connector X1 to the connector on USB2PMB1. 5) Connect the USB2PMB1 to the PC with the Mini-USB cable. Windows should automatically recognize the device and display a message near the System Icon menu indicating that the hardware is ready to use. 6) Once the hardware is ready to use, launch the software. The status bar in the GUI should display Disconnected in the bottom right-hand corner. Go to the Device tab to select the MAX14914PMB. 7) Click Update Once to read the default status of the MAX14914.
