Power Input Selection – Jumpers J2, J3, J5, J7, and connection terminal
Figure 4 shows the jumper settings and terminal connections for the three different modes of regulation. The board must be
power cycled after jumper settings are changed for the changes to take effect.
When using on-board regulation. Connections should be made to PWR2 and GND only. Provide a supply voltage between 4.0
and 5.5V capable of delivering the required charge current to the cells.
When using on-board regulation with a separate supply for the DS2711/12, connect the DS2711/12 supply voltage between
PWR1 and GND, connect the charge source between PWR2 and GND.
When using an externally regulated charge source, connect the DS2711/12 supply voltage between PWR1 and GND and
connect the regulated charge source between PWR3 and GND. Leave PWR2 open. The CSOUT terminal will supply a linear
feedback voltage that can be used to regulate the supply current.
