Figure 5. Microprocessor-Interfaced Li+ Charger with the MAX8804Y/MAX8804Z
Connect the input capacitors as close as possible to
the IC. Provide a large copper GND plane to allow the
exposed paddle to sink heat away from the IC. Connect
the battery to BAT as close as possible to the IC to pro-
vide accurate battery voltage sensing. Make all high-
current traces short and wide to minimize voltage
drops. A sample layout is available in the MAX8804Z
evaluation kit to speed designs.
