Charging Current Setting
SET is a logic input that sets DC/USB charging mode
and charging current. Drive SET low or leave it uncon-
nected to enable DC charging mode. Drive SET high to
enable USB charging mode (see Table 1). SET can
also be driven by series pulses to program the charg-
ing current in both DC and USB mode.
DC Charge Mode
Drive SET low or leave it unconnected to enable DC
charging mode. Subsequent pulses on SET program
the charging current and the top-off threshold. There
are seven fast-charge current options and four top-off

threshold options. Pulse SET high (1μs to 1ms pulse
width) subsequently to realize charging current and
top-off threshold programming and transition. After the
28th pulse, the MAX8804V/ MAX8804W/MAX8804Y/
MAX8804Z go into the default mode and start a new
cycle. See Tables 2, 3, and 4 and Figure 3 to set the
desired charging current and top-off threshold. Drive
SET high longer than 2ms to disable the DC charging-
control circuitry.
