2 / 11 page Maxim Integrated │ 2 www.maximintegrated.com Evaluates: MAX77816 MAX77816 Evaluation Kit Quick Start Required Equipment ● MAX77816 EV kit ● MAX77816 EV kit software (GUI) ● Maxim’s MINIQUSB (optional, USB cable included) ● Adjustable DC power supply capable of supplying 6V 9A ● Digital multimeters ● Electronic load capable of sinking 4A ● Oscilloscope (optional) Note: In the following sections, software-related items are identified by bolding. Text in bold only refers to items directly from the EV kit software. Text in bold and under- lined refers to items from the Windows OS. Procedure The EV kit is fully assembled and tested. Follow the steps below to verify board operation. Use twisted wires of appropriate gauge (20AWG) that are as short as possible to connect the load and power sources. 1) Confirm all jumpers are in their default positions as indicated in Table 1. 2) Preset the DC power supply to 3.8V. Do not turn on the power supply until all connections are completed. 3) Set up the test circuit as shown in Figure 2. Ad- just the ammeters to their largest current range to minimize their series impedance. Do not allow the ammeters to operate in their auto-range mode. If current readings are not required, short across the ammeters. 4) Turn on the power supply. 5) Switch JU2 to OUT1(1-2) to enable the IC. Verify that the voltage at OUTBBS is 3.4V (default output voltage setting). 6) Enable the electronic load and apply load current as required. 7) The EV kit software can be downloaded from www. maximintegrated.com/evalkitsoftware. If I2C control is required, install the EV kit software on to your computer by running the installation file (MAX77816GUISetup1.70605.0A.EXE). The pro- gram files are copied and a shortcut icon is created in Windows Start | Programs. 8) Connect the MINIQUSB to J1. Connect a USB cable from the PC to the MINIQUSB. 9) Start the EV kit software by opening its icon in the Start | Programs. The EV kit software main window appears. Click on Device then Connect. If connec- tion is successful, a window displaying the message Currently connected to CMOD “MINIQUSB” and device “MAX77816” appears as shown in Figure 3. Click Read and Close. 10) The EV kit and GUI are now ready for use. Figure 2.
