UG127 Rev 1.0, 14-Jun-2018 ACT510xEVK1-102 User's Guide Description This document describes the characteristic and operation of the Active Semi ACT5101EVK1-102 and ACT5102EVK1-102 evaluation kits (EVK). It provides setup and operation instructions, schematic, layout, BOM, and test data. The ACT5101EVK1-102 demonstrates the ACT5101QI102 power management IC. The ACT5102EVK1-102 demonstrates the ACT5102QI102 power management IC. Other ACT5101QIxxx and ACT5102QIxxx options can be evaluated on these EVKs by replacing the IC and any other necessary components. The two EVKs are very similar. The difference is that the ACT5101 output voltage is set by internal registers and it has A/D functionality. The ACT5102 output voltage is set by external resistors and it does not have A/D functionality. The setup and operation of the two EVKs are identical, so this document only references the ACT5101. Features The EVKs can be used as a standalone boards if desired. However, to access the internal registers and to take full advantage of the IC's capability, the user must connect the EVK kits to a PC with Active Semi's USB-TOI2C interface dongle and use the GUI software. The EVK provides full access to the each converter's input and output voltage, as well as all the digital control signals. This gives the user the flexibility to configure the EVK to match their real world system.

Connect Digital Multi-Meters to VIN and VOUT to monitor the input voltage and output voltages. 4. Add a digital Multi-Meter in series with VIN and VOUT if you want to observe input and output current. 5. Be careful to keep the input voltage and battery voltage within the specifications. 6. Add a jumper to J6 to connect INTBP to V_IO. 7. Optional - Connect the EVK to the PC with the USB dongle. 8. Apply input power. Note that the out GUI Setup (optional) 1. Refer to the end of this document for detailed instructions to install the ACT5101 GUI. 2. Connect the USB-TO-I2C dongle to the computer via a USB cable. 3. Connect the USB-TO-I2C dongle to the EVK J5 connector. Refer to Figure 3 to ensure the correct polarity of the connection. As a guide, use the "Active-Semi" logo on the top of the dongle so the black wire is connected to the Dongle GND pin.

The maximum operating voltage is determined by the IC's maximum input voltage rating. The minimum operating voltages are determined by the buck-boost converter's minimum input voltage. Maximum currents are determined by the IC's CMI settings, which can be changed via I2C after startup. Operating currents are configured by CMI and external components. Table 1. Recommended Operating Conditions Parameter Description Min Typ Max Unit VIN Charger input voltage 4 - 22 V VOUT Charger output voltage 3 - 20 V IIn_max Maximum input current 5 A Iout_max Maximum output current 5 A IREG_max Maximum LDO VREG load current 0.1 A EVK Operation Turn On the Evaluation Board Before applying the input voltage, please make sure the jumper (J6) is installed. Connect V_IO to INTBP or VREG. INTBP is the typical connection. Figure 4 - Hardware Configuration After the power source and E-Load are connected to the evaluation board per the required connections, the EVK can be powered for operation. Perform the following steps to turn on the board. 1. Ensure that the power supply connected to VIN (J1) is >4V and <22V. 3. Turn on power supply. 4. Apply the load. Input Current Limit Configuration The ACT5101's ActivePath charger features configurable input and output current limit. These features are programmed with a combination of an external resistor and an internal I2C register. Refer to the ACT5101 datasheet for programming details. Input Current Limit - The ACT5101EVK1-102 EVK input current limit is set to 11.11A. This is a function of the 5m current sense resister, R2, the 36k RILIM resistor, R6, and the I2C Input Current Limit bits, INLIMIT, which are set to 200% by default. The hardware current limit set by R2 and R6 is 5.56A. This current multiplied by the input current limit scaling factor of 200% gives a 11.11A input current limit. The input current limit is easily changed by modifying any of these three parameters. The easiest way to change the input current limit is with the Input Current Limit field in the GUI. Innovative PowerTM ActiveSwitcherTM is a trademark of Active-Semi. 4 UG127 Rev 1.0, 14-Jun-2018 Output Current Limit - The ACT5101EVK1-102 EVK output current limit is set to 5A. This is a function of the 10m current sense resister, R16, the 20k RILIM resistor, R12, and the I2C Input Current Limit bits, CC, which are set to 100% by default. The hardware current limit set by R16 and R12 is 5A. This current multiplied by the input current limit scaling factor of 100% gives a 5A output current limit. The output current limit is easily changed by modifying any of these three parameters. The easiest way to change the output current limit is with the Output Constant Current field in the GUI. Output Voltage Setting ACT5101 5.1V default output voltage can be changed I2C using the Output Voltage field GUI setting. Additional Programmable Functionality The ACT5101 contains many additional programmable parameters. Refer to the ACT5101 datasheet for additional functionality and default I2C register values.

Get GUI files from the Active Semi website Plug the USB-TO-I2C dongle into a free USB port. Follow the instructions in the "How to install driver for dongle" folder. Double click on the ACT5101 GUI.exe to start the ACT5101 GUI. GUI Overview The GUI has 2 basic function buttons allocated in top-left of the Tool Bar which are Read and Write I2C. The GUI contains 2 setting modes: Basic Mode and Advanced Mode. In Basic Mode screen it displays basic user programmable configuration options are programmed using the drop-down boxes or check boxes. Advanced Mode contain the button text for changing setting for every single bit. Basic Mode The following figure show the GUI in basic mode. This mode allows the user to easily change one or more IC settings. Innovative PowerTM ActiveSwitcherTM is a trademark of Active-Semi. 17 UG127 Rev 1.0, 14-Jun-2018 Advanced Mode Click the "Advanced Mode" button in the left of the GUI screen to see all available user programmable options. With Advanced Mode, additional user programmable features can be selected using the button text. In the left side of the Advanced Mode Screen, click on the Tiles Selector to display the register to view or change. Then change a register one bit at a time by clicking on the desired bit. The value of the bit is display right next to the bit-name button. Note that the far right side of the screen contains a scroll down button to scroll down to additional registers since the Tile Screen can only display up to 8 bytes at once. Innovative PowerTM ActiveSwitcherTM is a trademark of Active-Semi. 18 UG127 Rev 1.0, 14-Jun-2018 Button Descriptions Read: Clicking on this button reads the ACT2861 registers and displays them in the GUI. Note that this reads all registers. Active-Semi recommends reading registers each time the ACT2861 powers-up to acquire the initial register settings. Active-semi also recommends reading registers after making changes to them. Immediately reading the registers after a write confirms the changes were properly stored. Read Button Write: Clicking on this button writes the GUI settings to the ACT2861's registers. All registers are written, regardless of whether or not they were changed. Write Button Dongle Connection Status: The GUI also contains a dongle connection status that indicates Active-Semi's USB-TO-I2C dongle is connected to the USB port. The figure below shows the two possible indication status graphics. Dongle connected Dongle Disconnected Innovative PowerTM ActiveSwitcherTM is a trademark of Active-Semi. 19
