15/20 xc6413/ x c6414 series for the xc6403/04b series, there are two types of toggle select ion; one is a t-type flip-flop (t-ff) used for toggle operation which can be reset internally by a signal directly from the voltage detector (v in sense type only. see also the selection guide). the other type is where the reset is app lied internally through a one shot pulse circuit (v in , v rout type only. see also the selection guide). the type, which applies the reset directly via the signal from the voltage detector function, applie s 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, apply a voltage larger than the release voltage to v in and input a toggle signal to the t-ff. in the case where input voltage 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 (v in sense type) and output voltage (v rout sense type) drop below the detect voltage level. this type can return the vr output by inputting a toggle signal, even when the sense pin voltage (v in or v rout pin voltage) is below the release voltage. please refer to the block diagram below and the timing chart on the following page. please choose the option suitable to the application. block diagram for xc6413/14b series timing chart operational explanation (continued) block diagram for the xc6413 / 14b series? timing chart
