Monolithic Ic Mm1026, 1245, 1080 ,1134 Electric Semiconductor

These ICs protect MM1026 MM1245 MM1080 MM1134 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 drops. Conversely, when power supply rises, it first switches the S-RAM from battery back-up to main power supply (switching voltage 3.3V typ.), then from back-up mode to normal mode (CS signal makes S-RAM CE pin high and CE pin low). These signal processes provide reliable protection against data damage By Mitsumi Electronics, Corp.
