Battery Protection DWA01A SMD

Description

The DW01A battery protection IC is designed to protect the lithium-ion / polymer battery from damage or degrading the lifetime due to overcharge, overdischarge, and / or overcurrent for single-cell lithium-ion / polymer battery powered systems, such as cellular phones.
The ultra-small package and less required external components make it ideal for integrating the DW01A into the limited space of the 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.

Specification:
Reduction in Board Size due to Miniature Package SOT-23-6.
Ultra-Low Quiescent Current at 3μA (Vcc = 3.6V).
Overdischarge Current at 4μA (Vcc = 1.8V).
Precision Overcharge Protection Voltage 4.3V ± 50mV
Two Detection Levels for Overcurrent Protection.
Delay times are generated by internal circuits. No external capacitors required. Temperature Range -40 ° C ~ + 85 ° C.
Protection IC for One-Cell Lithium-Ion / Lithium-Polymer Battery Pack.
