RT4823

Description

The RT4823 integrates built-in power transistors, synchronous rectification, and low supply current to provide a compact solution for systems using advanced Li-Ion battery chemistries. The RT4823 is capable of supplying significant energy when the battery voltage is lower than the required voltage for system power ICs.
