_______________Detailed Desc ription
Output Charac teristic s
The MAX1647/MAX1648 contain both a voltage-
regulation loop and a current-regulation loop. Both
loops operate independently of each other. The volt-
age-regulation loop monitors BATT to ensure that its
voltage never exceeds the voltage set point (V0). The
current-regulation loop monitors current delivered to
BATT to ensure that it never exceeds the current-limit
set point (I0). The current-regulation loop is in control
as long as BATT voltage is below V0. When BATT volt-
age reaches V0, the current loop no longer regulates,
and the voltage-regulation loop takes over. Figure 5
shows the V-I characteristic at the BATT pin.
