The PW3130 series product is a high integration solution for lithium-lion/polymer batteryprotection.PW3130 contains advanced power MOSFET, high-accuracy voltage detection circuits anddelay circuits. PW3130 is put into an ultra-small SOT23-5 package and only one external componentmakes it an ideal solution in limited space of battery pack. PW3130 has all the protection functionsrequired in the battery application including overcharging, overdischarging, overcurrent and loadshort circuiting protection etc. The accurate overcharging detection voltage ensures safe and fullutilization charging.The low standby current drains little current from the cell while in storage. Thedevice is not only targeted for digital cellular phones, but also for any other Li-Ion and Li-Polybattery-powered information appliances requiring long-term battery life
The PW2312 is a high frequency, synchronous, rectified, step-down, switch-mode converter withinternal power MOSFETs. It offers a very compact solution to achieve a 1.5A peak output currentover a wide input supply range, with excellent load and line regulation.The PW2312 requires a minimal number of readily available, external components and is available ina space saving SOT23-6 package.
