Intersil ICL7673 Data Sheet
The ICL7673 is a monolithic CMOS battery backup circuit designed to switch between a main power source and a battery backup. It provides low‑loss, low‑current consumption switching for volatile CMOS RAM, real‑time clocks, and other low‑power applications.
The device includes comparator‑driven MOS switches, logic indicator outputs, and optional external PNP transistors for higher current capability. Typical performance includes a 2.5 V–15 V input range, 50 µs switching time, and very low leakage currents.
