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 SL326 battery protection IC is design ed 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 SL326 into the limited space of battery pack. The accurate ±25mV overcharging detection voltage ensures safe and full utilization charging. The very low standby current drains little current from the cell while in storage.

Features

● Reduction in Board Size due to Miniature Package SOT-23-6.

● Ultra-Low Quiescent Current at 3μA (Vcc=3.9V).

● Auto recovery

● 0v charging

● Precision Overcharge Protection Voltage 4.375V ± 25mV for the SL326

● Load Detection Function during Overcharge Mode.

● Two Detection Levels for Overcurrent Protection.

● Delay times are generated by internal circuits. No external capacitors required.

Applications

● Protection IC for One-Cell Lithium-Ion /Lithium-Polymer Battery Pack：

-built-in cell of mobile phone

-digital product cell

-camera cell

-portable power

● Reflow soldering internal actual temperature < 250 degrees, time in high temperature < 7 s.
