ROHM Semiconductor BA6162
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.| Part No. | BA6162 |

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 battery.●Absolute maximum ratings (Ta = 25°C) Parameter Power supply voltage Output current 1 Output current 2 Power dissipation Operating temperature Storage temperature Symbol VCC IOUT1 IOUT2 Pd Topr Tstg Limits 7.0 – 80 (BA6129AF) – 40 (BA6162 / BA6162F) – 200 900∗1 (BA6162) 550∗2 (BA6129AF) (BA6162F) – 20 ~ + 75 – 40 ~ + 125 °C °C Unit V mA µA mW IOUT1 indicates the output current on the VCC side, and IOUT2 the output current on the VBAT side. ∗1 Reduced by 9.0mW for each increase in Ta of 1°C over 25°C. ∗2 Reduced by 5.5mW for each increase in Ta of 1°C over 25°C. 1 Memory ICs BA6129AF / BA6162 / BA6162F
