Fortune Semicon DW01+G

The DW01 series 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 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.

• Reduction in Board Size due to Miniature Package SOT-23-6.
• Ultra-Low Quiescent Current at 3μA (Vcc = 3.9V).
• Ultra-Low Power-Down Current at 0.1μA or Overdischarge Current at 3.5μA (Vcc = 2.0V).
• Precision Overcharge Protection Voltage 4.25V~4.35, accuracy of ± 50mV.
• 0V battery change function are selectable.
• Power-down fuction are selectable.
• Load Detection Function during Overcharge Mode.
• Two Detection Levels for Overcurrent Protection.
• Delay times are generated by internal circuits.
• No external capacitors required.
