Note: In the following sections, software-related items are identified by bolding. Text in bold refers to items directly from the EV kit software. Text in bold and underlined refers to items from the Windows operating system. Required Equipment MAX77714 EV kit Dual power supply with 6V and 5A capability Figure 2: Connecting to the EV Kit Digital voltmeter (DVM) Ammeter Micro-USB cable Procedure The EV kit is fully assembled and tested. Follow the steps below to verify board operation: 1) Install GUI software. Visit www.maximintegrated. com/evkitsoftware to download the latest version of the EV kit software. Save the EV kit software to a temporary folder and decompress the ZIP file. 2) Install all shunts as recommended in Table 1. 3) Connect a disabled 3.6V bench power supply through an ammeter to VIN and GND wire loops. Set the input current limit of the bench supply to 3A. Do not enable the output of the bench supply until prompted. 4) Enable the output of the 3.6V bench power supply. 5) Connect a Micro-B USB cable between the EV kit and the PC and EV kit. 6) Wait a few seconds for the computer to install the Figure 3: Connecting to the MAX77714 USB driver.
