MM1026B
MM1026B - Brand New Powerex IC Chips
- One-month free return and one year warranty.
- Full or Partial Refund, if the item is not as described
- Full Refund if you don't receive your order
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 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
• Power supply switching circuit (switching between main power supply and
battery)
• 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)
• Reset output
MM1245
• Power supply switching circuit
• CS control for S-RAM
• CS control signal delay, power supply line chattering removal approx. 1S
max.
• Supply current from main power supply can be increased by external power
transistor
MM1080
• Power supply switching circuit
• CS control for S-RAM
