Milpitas, Calif. The LTC4006 is a 2- to-4-cell battery charger with up to a 4-A charge capability that includes the essential I/O status signals required to construct a simple autonomous battery charger system. Housed in a 16-pin SSOP, the device delivers a 96-percent operating efficiency when working across the 6- to 28-V supply range. The device can also operate from a 98% duty factor, which permits 0.5-V dropout operation and allows charging from low-voltage wall adapters.
To improve safety during charging, the IC features a battery temperature monitor as well as overvoltage and overcurrent protection. Target applications include mobile devices and notebook PCs.
