DW01MC-x
General Description
The DW01M battery protection IC with built-in N-MOSFET 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 DW01M 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
• | Built-in N-MOSFET of low turn-on resistance. | • | Reduction in Board Size due to Miniature Package TSSOP-8 or SOT-23-6 or DFN-5. | • | Protection IC: | | • | Ultra-Low Quiescent Current at 3μA (Vcc=3.9V). | | • | Overcharge Protection Voltage 4.3V ± 50mV | | • | Overdischarge Protection Voltage 2.4V ± 100mV | | • | Overcurrent Protection Voltage 150mV ± 30mV | | • | Auto Recovery function | • | MOSFET: | | • | Rss(ON) < 55mΩ (VGS = 3.7V , ID = 1A) |
