MP2606 – SINGLE CELL 1A LINEAR LI-ION BATTERY CHARGER W/O TRICKLE CHARGE
Charge Status Indicator (
)
CHG
The MP2606 has an integrated charge status
pin that remains low while the battery is
charging. Once the charge current has reduced
to the battery full charge current threshold (I
),
BFL
the
pin will become high impedance.
CHG
Thermal Protection
The MP2606 has proprietary thermal protection
to prevent the IC from overheating. When in
thermal protection mode, the charge current
becomes a saw-tooth waveform instead of a
DC current. The average current of the saw-
tooth
waveform
will
be
lower
than
the
programmed DC charge current to prevent the
IC from overheating. The frequency and
amplitude of the saw-tooth current waveform
can be altered by changing the capacitance
value connected to the SS pin. Operating in
thermal protection mode will slow down the
charging process. Lowering the input voltage
and enhancing thermal dissipation to the
environment can effectively prevent the IC from
going into thermal protection mode.
