Detailed Description
The MAX8808X/MAX8808Y/MAX8808Z chargers use
voltage, current, and thermal-control loops to charge a
single Li+ cell and protect the battery (
Figure
1). When
a Li+ battery with a cell voltage below 2.5V is inserted,
the MAX8808X charger enters the prequalification
stage where it precharges that cell with 10% of the
user-programmed fast-charge current (
Figure
2). The
CHG
indicator output is driven low to indicate entry into
the prequalification state. When battery voltage
exceeds 2.5V, the charger soft-starts as it enters the
fast-charge stage. In the MAX8808X/MAX8808Y/
MAX8808Z, the fast-charge current level is pro-
grammed through a resistor from ISET to GND. As the
battery voltage approaches 4.2V, the charging current
is reduced. If the battery current drops to less than
10% of the fast-charging current, the
CHG
indicator
goes high impedance, signaling that the battery is fully
charged. The ICs then enter a constant voltage-regula-
tion mode to maintain the battery at full charge.
