ICS1702EB Galaxy Power, Inc., ICS1702EB Datasheet - Page 5

• Manufacturer Part Number: ICS1702EB
• Description: Ics1702 Evaluation Board.
• Manufacturer: Galaxy Power, Inc.

When designing the printed circuit board, make sure ground and
power traces are wide and bypass capacitors are used right at the
controller pins. Use separate grounds for the signal, charge, and
discharge circuits. Separate ground planes on the component side
of the PC board are recommended. Be sure to connect these
grounds together at the negative lead of the battery only.
For the discharge circuit, keep the physical separation between
power and return (ground) to a minimum to minimize field
radiation effects. This precaution is also applicable to the constant
current source, particularly if it is a switch mode type. Keep the
ICS1702 and the constant current source control circuits outside
the power and return loops described above. These precautions
prevent high circulating currents and coupled noise from disturbing
proper operation.
Galaxy Power Incorporated wants to help create a successful
battery charging solution using the ICS1702. If you need technical
advice or applications information, call the Intelligent Charging
Solutions hotline at [phone] x-277.
