DW01A 1. General Description Ordering Information DW01A-G PACKAGE TYPE SOT-23-6(G stands for Green-Package) TEMPERATURE RANGE -40°C~+85°C OVERCHARGE PROTECTION 4.3V± 50mV FO Fo P R r R ro TU ef pe NE er rti ’ en es ce O nl 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 / Lithium-Polymer Battery Pack 3/14
