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 automatically to battery back-up if the main power supply voltage goes down for any reason.
