■OPERATIONAL EXPLANATION
(Especially explained for the CMOS output products)
① When input voltage (VIN) is higher than detect voltage (VDF), output voltage (VOUT) will be equal to VIN.
(A condition of high impedance exists with N-ch open drain output configurations.)
② When input voltage (V
SS) level.
(V
IN) falls below detect voltage (VDF), output voltage (VOUT) will be equal to the ground voltage
③ When input voltage (VIN) falls to a level below that of the minimum operating voltage (VMIN), output will become
unstable.(As for the N-ch open drain product of XC61CN, the pull-up voltage goes out at the output voltage.)
④ When input voltage (V
minimum operating voltage (V
IN) rises above the ground voltage (VSS) level, output will be unstable at levels below the
MIN). Between the VMIN and detect release voltage (VDR) levels, the ground voltage (VSS)
level will be maintained.
⑤ When input voltage (V
IN) rises above detect release voltage (VDR), output voltage (VOUT) will be equal to VIN.
(A condition of high impedance exists with N-ch open drain output configurations.)
⑥ The difference between V
DR and VDF represents the hysteresis range.
