Overview
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 automatically to battery back-up if the main power supply voltage goes down for any reason.
Features 1.
Battery back-up MM1025 Current consumption Input/output voltage difference IL=40mA Output current MM1174 Current consumption Input/output voltage difference IL=40mA Output current 2.
Normal operation MM1025 Input/output voltage difference IL=80mA (built-in transistor) Output current VCC=6V External transistor drive current VCC= 6V Current consumption MM1174 (for external transistor) Input/output vol...
