XC6413/XC6414

Series

<Toggle Operation (Continued) >

For the XC6403/04B series, there are two types of toggle selection; one is a T-type flip-flop (T-FF) used for toggle operation

also the Selection Guide). The type, which applies the reset directly via the signal from the voltage detector function, applies

the voltage detector comparator's output signal (reset signal) to the reset of T-FF reset, and turns the VR output OFF when

the input voltage decreases below the detect voltage due to battery consumption, etc.. In order to return the VR output,

is below the release voltage, the VR output does not return even though the toggle signal is input into the T-FF.

The type which applies the reset signal to the T-FF internally via a one-shot pulse circuit changes the voltage detector

comparator output signal to a one-shot signal internally. Like the type which applies the reset directly via the signal from

voltage detector function, this type also applies the reset to the T-FF and sets the VR output to OFF when the input voltage
