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.
