NJU7700/01 (cid:132) FUNCTIONAL DESCRIPTION (1) Basic operation Supply voltage (1) When supply voltage(V ) drops below (V ) Hysteresis voltage DD DD (V ) detection voltage(V ), Output voltage(V ) HYS Release voltage DET OUT (V + V ) changes "H" to "L" to alert reset state. Detection voltage DET HYS (V ) (2) The reset state is kept while V is lower than DET DD release voltage. The release voltage is a sum Minimum operation voltage (V ) of V and Hysterisis voltage (V ). Please OPL DET HYS V refer to the (*7) below. SS (3) When V becomes higher than the release DD Output voltage voltage, then V changes from "L" to "H" to OUT (V ) OUT resume normal state. (*7) V is to avoid unstable V state caused HYS OUT by rapid voltage change at nearby V . DET V SS (*8): C-MOS output product (NJU7701) : When V less than V , V is free of the shaded region.
