When input voltage falls below VDET-, output will pull down logic after delay time tpHL. general, rated output current VCC, VOUT pulled down voltage within 0.4V from GND. (See Electrical Characteristics section). voltage level VDET- means detect voltage. output, VOUT, will stay valid until falls below minimum operating voltage, VOPR (0.8V typical). Below minimum operating voltage, output undefined. During power-up, VOUT will remain undefined until rises above VOPR, which time output will become valid. VOUT will active state while VOPR<VCC<VDET+ (VDET+=VDET-+VHYS). VDET+ release voltage. VHYS means hysteresis voltage difference voltage between VDET+ VDET-. When rises above VDET+, output will inactive state. After delay time tpLH, VOUT will logic high state
