The ultra-small package and less required external components make it ideal to integrate the DW01 series 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. 2. 4. z Applications Protection IC for One-Cell Lithium-Ion / Lithium-Polymer Battery Pack Features z Reduction in Board Size due to Miniature Package SOT-23-6. z Ultra-Low Quiescent Current at 3μA (Vcc=3.9V). z Ultra-Low Power-Down Current at 0.1μA or Overdischarge Current at 3.5μA (Vcc=2.0V). z Precision Overcharge Protection Voltage 4.25V~4.35, accuracy of ± 50mV. z 0V battery change function are selectable. z Power-down fuction are selectable. z Load Detection Function during Overcharge Mode. z Two Detection Levels for Overcurrent Protection. z Delay times are generated by internal circuits. No external capacitors required. Rev. 1.7 3/19 DW01x 5.
