Description
Open?collector, active?low output of the input voltage detector with hysteresis. Threshold levels are
typical 7.0 V/ 7.35 V at V CC pin.
Active?low output of the reset generator. Reset generator is based on sensing of the V out1 voltage.
Sensing is with hysteresis ? threshold levels are typically 2.9 V/ 2.95 V at V out1 . Reset is generated at
rising edge of the V out1 and it’s duration is set by external capacitor connected to C D pin.
Programmable delay of the reset generator. Delay is adjusted by inserting a capacitor between C D and
GND (typically 10 ms for 10 nF capacitor).
