The MAX17005B/MAX17006B/MAX17015B feature a
voltage-regulation loop (CCV) and two current-regula-
tion loops (CCI and CCS). The loops operate indepen-
dently of each other. The CCV voltage-regulation loop
monitors BATT to ensure that its voltage never exceeds
the voltage set by VCTL. The CCI battery charge cur-
rent-regulation loop monitors current delivered to BATT
to ensure that it never exceeds the current limit set by
ISET. The charge current-regulation loop is in control as
long as the battery voltage is below the set point. When
the battery voltage reaches its set point, the voltage-

regulation loop takes control and maintains the battery
voltage at the set point. A third loop (CCS) takes control
and reduces the charge current when the adapter cur-
rent exceeds the input current limit.
The MAX17005B/MAX17006B/MAX17015B have single-
point compensation. The two current loops are internal-
ly compensated while the voltage loop is compensated
with a capacitor at CC pin. A functional diagram is
shown in Figure 2.
