XC6140 Battery Voltage Monitoring ICs Torex Semiconductor XC6140 Battery Voltage Monitoring ICs are optimal for CV rechargeable batteries and electric double-layer capacitors. These ICs output the release signal even in the voltage drop of the rechargeable batteries with high internal impedance due to inrush current. The output is released by setting the release voltage to 2.475V and increasing the hysteresis width. These XC6140 ICs make the subsequent system stop and stand by on the rear stage until the charging is completed when the battery voltage drops.
