MITSUMI System Reset (with battery back-up) MM1025, 1174 System Reset (with battery back-up) Monolithic IC MM1025, 1174 Outline These ICs were developed for D-RAM and dummy S-RAM battery back-up.

D-RAM and dummy S-RAM power supplies differ from that of S-RAMs because 5V or 3.3V of power supply is required even during battery back-up.

Therefore, these ICs provide voltage from a stable power supply during both normal operation and back-up.

Also, the internal stable power supply switches automat
