IC for System Reset (battery backup)

Outline These ICs protect S-RAM data in back-up mode (CS signal makes R-SAM CE pin low and CE pin high) when power supply voltage goes below a certain set voltage (detection voltage 3.5V, 4.2V or 4.5V typ.). Further, it switches from main power supply to battery back-up when power supply voltag

System Reset (with battery back-up)

Outline\nThese ICs protect S-RAM data in back-up mode (CS signal makes R-SAM CE pin low and CE pin high) when power supply voltage goes below a certain set voltage (detection voltage 3.5V, 4.2V or 4.5V typ.). Further, it switches from main power supply to battery back-up when power supply voltage dr MM1026\n• Power supply switching circuit (switching between main power supply and battery)\n• CS control for S-RAM (normal mode : S-RAM can be accessed; back-up mode: S-RAM can not be accessed low current consumption mode)\n• Reset output\nMM1245\n• Power supply switching circuit\n• CS control for S;
