ROHM Semiconductor 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. 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.| Part No. | BA6162F |
