DA9318 to be controlled via the USB port of a PC. The mini USB connection is visible on the left side of the board. When the cable is connected to the USB port of the PC the green LED (D1) is on.
UM-PM-022 DA9318 Direct Charging Reference Board Functional Description During direct charging the master charger of the battery operated device is bypassed and the TA is directly connected to the battery. The difference between normal charging and direct charging is illustrated in...
IN2OUT_MAX When the above conditions are satisfied the DA9318 can be enabled by writing CP_EN to allow for direct charging. The TA voltage is set accordingly to allow an initial 6 A charge current into the battery.
A sequence diagram for direct charging is depicted in Figure NOTE The DA9318 direct charging reference board communication to the TA is achieved using a Dialog proprietary secondary-side to primary-side digital link communication protocol. The sequence diagram in Figure 4 provided for information only.

Power Supplies The DA9318 direct charging board is powered up when a power source is connected to IN (J48). IN operating voltage range is +5.5 V to +10.5 V. The VDD_IO voltage is generated by an on-board regulator (VR1) supplied from the +5 V USB. By default, the on-board generated VDD_IO is +1.8 V (J26 jumper is POP, J27 jumper is UNPOP):...
® Windows 2000/XP/Vista/Windows 7 with a USB1.1 or USB2 interface. The GUI allows the user to: ● Perform raw write and read operations to all control registers on Dialog and non-Dialog ICs. ● Monitor the charging status. ● Plot the DA9318 efficiency over time with saving and zoom feature.
