Delay circuit
delay circuit outputs voltage detector output (VOR) with delay after voltage become release voltage (+VDET) rising pin. Figure when exceeds reference voltage (Vref), output voltage detection voltage output (VOR) changes from high level, providing delay output. When voltage falls under detection voltage (-VDET), transistor turns therefore charge external capacitor (CD) rapidly discharged voltage detector output (VOR) changes from high level without delay. external capacitor (CD) charged with constant current, practically independent voltage. delay time (tpd) expressed following equation: (ms)=Delay coefficient (3.18 min., 5.74 typ., 8.73 (nF)
Vref
Figure Caution Unless output delay needed, keep open. apply external voltage other than ground potential pin, which cause breakdown. When designing your printed-circuit board layout, take care that leakage current flows external capacitor (CD), otherwise correct delay time obtained. Because value constant current source (IC) only impedance high.

Voltage detection circuit
built-in voltage detection circuit (Nch opendrain type) equivalent S-808 Series/S-809 Series voltage detectors. pull-up resistor about required output. Since comparator power this circuit supplied from pin, this circuit operates while voltage applied pin. detection voltage voltage detector selected follows: 11.3 V±2.4 (0.1 step) type, release voltage (+VDET) accuracy ±1.1 responds application overcharge detection lithium-ion battery packs. type, input voltage monitoring voltage detector externally connected SENSE pin. Because this configured resistor only, temporary current such through-type current does flow. Consequently even when resistor (RIN) inserted between input power supply pin, input power voltage accurately monitored connecting SENSE input power supply. Also, when drop SENSE input voltage detected, voltage detector generates reset signal. same time, powers voltage regulator.
Caution shown Figure when connecting output type connecting SENSE type, following phenomena occur resistor (RIN) connected between input voltage pin. careful. time voltage detection, voltage regulator shutdown load current cut. Therefore, voltage increases where current flowing into IIN. Hence, exceeds hysterisis width (VHYS), oscillation starts immediately after detection continues. necessary less than VHYS. time voltage release, voltage regulator powered load current flows. Therefore, exceeds hysterisis width (VHYS), oscillation starts immediately after release continues. necessary less than VHYS. Also time voltage release, rush current charge output capacitor (COUT) flows. Hence, oscillation momentarily starts until output regulator (VOUT) rises high enough even though less than VHYS. Short-circuit protection circuit controls rush current less than IMAX Figure this momentary oscillation problem your applicaion, setting less than VHYS/IMAX prevents oscillation.
