Our advantages

Chinese manufacturing processes have undergone years of iteration, resulting in mature and reliable technologies. Many international corporations opt for production outsourcing in China.  As an electronic components manufacturer in China, our products can fully replace those of major international brands in 99% of applications without the need for testing verification. Our products boast high consistency in quality, reasonable pricing, ample inventory, flexible supply, short lead times, and professional after-sales service. 

Description

The DW03 series product is a high integration solution for lithium-lion/polymer battery protection.DW03 contains advanced power MOSFET, high-accuracy voltage detection circuits and delay circuits. DW03 is put into an ultra-small SOT23-5 package and only one external component makes it an ideal solution in limited space of battery pack. dw03 has all the protection functions required in the battery application including overcharging, overdischarging, overcurrent and load short circuiting protection etc. The accurate overcharging detection voltage ensures safe and full utilization charging.The low standby current drains little current from the cell while in storage. The device is not only targeted for digital cellular phones, but also for any other Li-Ion and Li-Poly battery-powered information appliances requiring long-term battery life.
