Ultra-Small Package Built-In Delay High-Precision Voltage Detector  
CE8809 Series  
FUNCTIONAL DESCRIPTION  
1. When a voltage higher than the release voltage (+VDET) is applied to the voltage input  
pin (VDD), the voltage will gradually fall. When a voltage higher than the detect voltage  
(-VDET) is applied to VDD, output (VOUT) will be equal to the input at VDD.  
Note that high impedance exists at VOUT with the N-channel open drain configuration. If the  
pin is pulled up, VOUT T will be equal to the pull up voltage.  
2. When VDD falls below -VDET, VOUT will be equal to the ground voltage (VSS) level (detect  
state).  
Note that this also applies to N-channel open drain configurations.  
3. When VDD falls to a level below that of the minimum operating voltage (VMIN) output will  
become unstable.  
Because the output pin is generally pulled up with N-channel open drain configurations,  
output will be equal to pull up voltage.  
4. When VDD rises above the VSS level (excepting levels lower than minimum operating  
voltage), VOUT will be equal to VSS until VDD reaches the +VDET level.  
5 . Although VDD will rise to a level higher than +VDET, VOUT maintains ground voltage  
level via the delay circuit.  
6.  
Following transient delay time, VDD will be output at VOUT.  
Note that high impedance exists with the N-channel open drain configuration and that  
voltage will be dependent on pull up
