APL3208 Koreshige Delta Electronics (ANPEC Electronics Corporation) nikon EN-EL1 battery has launched a lithium battery charge current control IC, APL3208 output charge current total of Triple versions, namely 450,550, and 650mA. APL3208 can withstand a maximum input voltage 30V, a variety of protection functions will be integrated into a very small package, only minimal additional components are made APL3208 become the ideal handheld devices IC. Built-in protection features include: input voltage over-voltage protection, battery over-voltage protection, thermal protection, when one of the protection function is started, APL3208 will close built-in P-channel MOSFET Power Switch to rechargeable battery and charger power supply cut off, Each protection function are nikon EN-EL2 battery resistant to noise interference feature to prevent false triggering.
APL3208 more to prevent reverse battery to provide current to the charging function of the system, when the input voltage is lower than the battery voltage, the built-in P-channel MOSFET Power Switch will be closed in order to prevent the battery charging system of the discharge, APL3208 provides 2mmx2mm TDFN-8 Lead-Free package, temperature range up to -40 ℃ to +85 ℃.
Recently, Lenovo issued a public notice saying, ThinkPad series of notebooks are available in six models may be battery failure, the user can use the Lenovo battery diagnostic tools on their own testing, once they meet the conditions change, Lenovo will offer a free replacement battery.nikon EN-EL4 battery Lenovo side stressed that the replacement of the battery does not involve the issue of security risks.
According to statistics, ThinkPad series of notebooks were six kinds of models R60, R61, T60, T61, X60, X61; corresponding to the battery FRU (field replaceable unit) casio NP-30 battery respectively, 42T4546, 42T4566, 92P1141, 42T4550, 42T4567, 42T4568, 92P1169 , 92P1173, 93P5028, 93P5030
