Procedure
Battery Over-Voltage Protection and
Automatic Recharge
At any time when VBATT is 50mV higher than the
trimmed charge target, the MP2602 reduces its
charge current to 0µA. This ensures the safety
of the battery. Also, the CV control loop always
monitors the battery voltage such that it will
automatically recharge the battery when it is
depleted below the target level.
Programming of Charge Current and Battery
Full Current
The charge current (ICHG) is set by a resistor
(RCHG) connecting from the ISET pin to GND.
The relationship of the charge current and the
programming resistance is established by the
following table and graph.

Resistance
The recommended resistance for programming
the charge current is 2.3kΩ<RCHG<11kΩ. The
battery full charge current threshold (IBF) is
programmed by connecting a resistor RBF from
the IBF pin to GND:

condition prevents the charger from charging,

will become a floating pin.
