SETUP AND INSTALLATION
BOARD CONNECTIONS
Connections to the TSSOP demonstration board are best made either by soldering directly to the pads or
by using cables with mini-grabber clips. Communication to the TSSOP board can be accomplished either
through the RJ-11 jack by connecting the provided standard six conductor RJ-11 cord.
Figures 1a and 1b show the recommended circuits to simulate charging and discharging. The Lithium-Ion
cell is connected between the P+ and P- pads. The battery charger/power supply or circuit load is
connected between the P+ and SGND pads. The evaluation software can be run in either configuration as
long as a cell is connected between the P+ and P- terminals providing a minimum of 2.5 volts to power
the DS2746.
