Figure A:
Applications Information
To ensure proper operation of the
ICS1708
, external components must be properly selected. The external current source used must meet
several important criteria to ensure adequate performance of the charging system. The charging current source amplitude should be fairly
constant
VIN and OPREF Divider Resistors
Figure 9 shows a typical application using the
ICS1708
. R1 through R3 must be selected properly to ensure that battery detection and
voltage termination methods operate properly. R1 and R2 are selected to scale the battery voltage down to the voltage of one cell. The
following table shows some typical values.

If the current source is a switch mode type, normal ripple current does not effect the ICS1708. However, the effects of line frequency ripple
may interfere with proper performance. R3, per Figure 9, can be used to set the open circuit (no battery) reference voltage on the OPREF
pin. The function of this pin is discussed in the
Open Circuit Reference
section.
