DW01C-G
General Description
The DW01C 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 DW01C 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.
Feature
| • | 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 (Vcc=2.0V). | | • | Precision Overcharge Protection Voltage 4.25V ± 50mV | | • | Load Detection Function during Overcharge Mode. | | • | Two Detection Levels for Overcurrent Protection. | | • | Delay times are generated by internal circuits. No external capacitors required. |
