y The DW01A 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.
The ultra-small package and less required external
components make it ideal to integrate the DW01A
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. 3. 4. 2. Features Reduction in Board Size due to Miniature
Package SOT-23-6. Ultra-Low Quiescent Current at 3μA
(Vcc=3.9V). Ultra-Low Overdischarge Current at 3μA
(Vcc=2.0V). Precision Overcharge Protection Voltage
4.3V ± 50mV Load Detection Function during
Overcharge Mode. Two Detection Levels for Overcurrent
Protection. Delay times are generated by internal
circuits. No external capacitors required. Rev. 1.1 Applications Protection IC for One-Cell Lithium-Ion /
