DW01+

The DW01+ is designed as a plus battery protection IC which protects 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.

DW01+ has seven features. (1)Reduction in board size due to miniature package SOT-23-6. (2)Ultra-low quiescent current at 3uA (Vcc=3.9V). (3)Ultra-low power-down current at 0.1uA (Vcc=2.0V). (4)Precision overcharge protection voltage 4.3V+/-50mV for the DW01+. (5)Load detection function during overcharge mode. (6)Two detection levels for overcurrent protection. (7)Delay times are generated by internal circuits. No external capacitors required. Those are all the main features.

Some absolute maximum ratings of DW01+ have been concluded into several points as follow. (1)Its input voltage between Vdd and Vss would be from Vss-0.3V to Vss+10V. (2)Its OC output pin voltage would be from Vdd-26V to Vdd+0.3V. (3)Its OD output pin voltage would be from Vss-0.3V to Vdd+0.3V. (4)Its CS input pin voltage would be from Vdd-26V ato Vdd+0.3V. (5)Its operating temperature range would be from -40°C to 85°C. (6)Its storage temperature range would be from -40°C to 125°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of DW01+ are concluded as follow. (1)Its supply current would be typ 3.0uA and max 6.0uA. (2)Its power-down current would be max 0.1uA. (3)Its overcharge protection voltage would be min 4.25V and typ 4.3V and max 4.35V. (4)Its overcharge release voltage would be min 4.05V and typ 4.10V and max 4.15V. (5)Its overdischarge protection voltage would be min 2.3V and typ 2.4V and max 2.5V. (6)Its overdischarge release voltage would be min 2.9V and typ 3.0V and max 3.1V. And so on.
