DW01+
The DW01 Plus battery protection IC is designed to
protect lithium-ion/polymer battery from damage or
degrading
the
lifetime
due
to
overcharge,
overdischarge,
and/or
overcurrent
for
one-cell
lithium-ion/polymer battery powered systems, such as
cellular phones.
PACKAGE TYPE
SOT-23-6
TEMPERATURE RANGE
-40°C~+85°C
The ultra-small package and less required external
components make it ideal to integrate the DW01 Plus
into the limited space of battery pack. The accurate
±50mV overcharging detection voltage ensures safe
and full utilization charging. The very low standby
current drains little current from the cell while in
storage.
OVERCHARGE PROTECTION
4.3V± 50mV

Protection IC for One-Cell Lithium-Ion /
Lithium-Polymer Battery Pack
Ultra-Low Quiescent Current at 3μA
(Vcc=3.9V).
Ultra-Low Power-Down Current at 0.1μA
(Vcc=2.0V).
Precision Overcharge Protection Voltage
4.3V ± 50mV for the DW01 Plus
Load Detection Function during Overcharge
Mode.
Two Detection Levels for Overcurrent
Protection.
Delay times are generated by internal circuits.
No external capacitors required.
