Voltage monitoring IC for rechargeable batteries with CV charging. (Release Voltage 2.45V, Hysteresis width 0.35V~0.85V, Ultra low power Voltage Detector.)

The XC6142 series are battery voltage monitoring ICs optimal to CV rechargeable batteries and electric double layer capacitors.

By setting release voltage to 2.45V and increasing the hysteresis width, it is possible to continue to output the release signal even in the voltage drop of the rechargeable batteries with high internal impedance due to inrush current. When the battery voltage drops, it is possible to make the subsequent system stop and stand by on the rear stage until the charging is completed by setting the output signal at detection state.

In addition, hysteresis width is selectable in the range from 0.35V to 0.85V. So based on the internal impedance or over discharge voltage of a rechargeable battery, hysteresis width can be decided.

The SSOT-24 as well as ultra-small and low profile package USPQ-4B05 are available contributing to miniaturization of portable devices and high densely mounting applications. Even when VIN voltage is lower than the minimum operating voltage, malfunction of the system can be avoided by the undefined operation prevention function which minimizes the rise of output voltage.
