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.
3) Low current dissipation when powered from battery.
4) Low voltage loss when powered from battery.
5) Smooth switching between power supply and bat-
tery.
•Absolute maximum ratings (Ta = 25°C)
