RT4805 Description

The RT4805 allows systems to take advantage of new battery chemistries that can supply significant energy when the battery voltage is lower than the required voltage for system power ICs. By bining built-in power transistors, synchronous rectification, and low supply current; this IC provides a pact solution for systems using advanced Li-Ion battery chemistries.
