... VDOUT will output according to the voltage level at VDSENSE voltage. For the XC6403A type, in stand-by voltage of the recovery voltage is present at the VROUT pin (from another power source), the VDOUT pin will be high impedance mode, and the pull up voltage will be output at VDOUT. By connecting the Cdelay pin to a capacitor (Cd), the XC6403F series can apply a delay time to VDOUT voltage when releasing voltage. The delay time can be calculated from the internal resistance, Rdelay (2MΩ ...

... In stand-by mode, the above input current can be reduced by connecting a pull-up resistor between VROUT and VDOUT. Note that as the XC6403 types of the XC6403A to D series are 'Active HIGH / No Pull Down' and XC6403 types of the XC6403A to D series are 'Active LOW / No Pull Up', operations will become unstable with the CE pin open (See the chart below). ...

... Operation> (Continued) For the XC6403B series, there are two types of toggle selection; 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 (VIN Sense type only. See also the Selection Guide on page 2). The other type is where the reset is applied internally through a one shot pulse circuit (VIN, VROUT type only ...
