System Reset (with battery back-up) MM1026, 1245, 1080, 1134
System Reset (with battery back-up)
Monolithic IC MM1026, 1245, 1080 ,1134
Outline
-------------------------------------------
These ICs protect S-RAM data in back-up mode (CS signal makes R-SAM CE pin low and C E 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.
Features
MM1026
鈥?Power supply switching circuit (switching between main power supply and battery)
