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.
