MP2681
CC/CV Controller
with Full Protection and Indication
The Future of Analog IC TechnolOognye Chip Solution for Power Tools Applications
DESCRIPTION
The MP2681 is a highly integrated Li-Ion or Li-
polymer switch mode battery charge controller
with full protection and status indication. This
part integrates a precision voltage reference
and charge status indications suitable for AC
adapter input and cradle charger applications.
The MP2681 automatically detects the battery
cell through a battery ID resistor and regulates
the battery voltage according to the
corresponding cell configurations: 3S1P, 3S2P,
4S1P, 4S2P, 5S1P and 5S2P. Then, the AC
adapter output is automatically regulated
according to the battery configuration chosen.
Additionally, if the battery pack does not have
an ID resistor, the charge termination voltage
can be configured by setting a dedicated
voltage to the ID pin according to the six pre-set
VID values representing each battery
configuration. The MP2681 charges the battery
in three phases: pre-charge, constant current
and constant voltage. Charge is terminated
when the current reaches a minimum set level.
An internal charge timer provides safety backup.
The MP2681 provides a fixed pre-charge mode
for deeply-discharged batteries and safety
features that include battery temperature
monitoring, NTC control, charge time-out and
fault control.
MP2681 is available in a 16-pin SOIC package.
