Introduction The ZSPM4521 Evaluation Board (EVB) contains the ZSPM4521 High-Efficiency Photovoltaic Battery Charger integrated circuit with recommended external components and test points (see Figure 2.1). The ZSPM4521 enables a complete battery charging system using a photovoltaic cell. Key parameters of the battery charger are ... -
Page 5: General Overview
EVB’s default ZSPM4521 configuration settings are desired, no I C™ operation is needed. Operating the ZSPM4521 EVB is straightforward. Once the Li-ion battery and input voltage are properly connected as described in section 4.1, simply set switch SW1 to the ON position (see Figure 2.1), which starts the charging of the battery. -

Evaluation Kit Manual Connecting the FTDI Cable to ZSPM4521 Eval Board: C™ cable to J6 of ZSPM4521 Evaluation Board being careful to Connect the female connector of the FTDI USB/ I use the orientation shown in Figure 8.1. The order of the leads in the cable from left to right is black, gray, and then orange. -
Page 10: C™ Programming Gui Overview
GUI shows “Disconnected,” ensure that the I C™/USB cable is connected to the computer and the driver is installed; then try again. If there is a problem reading values from the GUI, verify that ZSPM4521 EVB is powered Figure 9.1 The ZSPM4521 Graphic User Interface (GUI) -
Page 11: Status Section
Status Section Click on the “Read Status” button to read the current values of monitor registers of the ZSPM4521 on the EVB. Enabling the “Auto Poll” feature will automatically read the status bits at the time interval specified in the adjacent field. -
Page 12: Configuration And Configx Sections
“CONFIG1” through “CONFIG5” sections at the top right of the GUI shown in Figure 9.1. For advanced users who are knowledgeable in ZSPM4521 bit assignments (for details, refer to ZSPM4521_Data_Sheet_rev_X_xy.pdf), settings can be changed manually using the “Configuration” section at the bottom left of the GUI. -
