Reset IC with battery backup function

BA6129AF / BA6162 / BA6162F

The BA6129AF, BA6162, and BA6162F are reset ICs with a battery backup function, designed for equipment using

SRAMs and other similar components. These ICs are configured of a reset signal and CS signal output unit and a

power supply switching unit. If the BA6129AF detects that the power supply has dropped to 3.5V or lower, it outputs

the CS, CSB, and Reset signals to set the SRAM in backup mode. If the voltage drops to 3.3V or lower, the power

supply switches to the battery. With the BA6162 and BA6162F, in the same way, a power supply of 4.2V is detected,

and if the voltage drops to 3.3V or lower, the power supply switches to the battery. These ICs allow SRAMs to be

write protected and allow the system to be reset, in addition to switching between the power supply and the battery.

Applications

•

Equipment using SRAMs (cards, cassettes, facsimile machines, copiers, word processors, personal computers, etc.)

Features

•

1) Equipped with battery backup function.

2) Equipped with both CS signals (CS and CSB) and

Reset signals.

4) Low voltage loss when powered from battery.

5) Smooth switching between power supply and bat-

tery.

3) Low current dissipation when powered from battery.
