LTC1960CG#PBF

LTC1960 is a highly integrated battery charger and selector intended for portable products using dual smart batteries. A serial SPI interface allows an external microcontroller to control and monitor status of both batteries. A proprietary PowerPath architecture supports simultaneous charging or discharging of both batteries. Typical battery run times are extended by 10%, while charging times are reduced by upto 50%. It automatically switches between power sources in less than 10µs to prevent power interruption upon battery or wall adapter removal. The synchronous buck battery charger delivers 95% efficiency with only 0.5V dropout voltage, and prevents audible noise in all operating modes. Patented input current limiting with 5% accuracy charges batteries in the shortest possible time without overloading the wall adapter. It is used in applications such as portable computers, portable instruments etc.
