Cautions in Power ON/OFF (BU9794KV)  
Power supply sequence  
Please keep Power ON/OFF sequence as below waveform.  
VLCD  
VDD  
FigBU9794KV-5 Power supply sequence  
Caution in P.O.R circuit use  
This device has “P.O.R” (Power-On Reset) circuit and Software Reset function.  
Please keep the following recommended Power-On conditions in order to power up properly.  
Please set power up conditions to meet the recommended tR, tF, tOFF, and Vbot spec  
below in order to ensure P.O.R operation  
tF  
VDD  
Recommendation condition of tR, tF, tOFF, Vbot (Ta=25℃)  
tR  
tR  
tF  
tOFF  
More than  
20ms  
Vbot  
Less than 5ms Less than 5ms  
Less than 0.3V  
tOFF  
Vbot

If it is difficult to meet above conditions, execute the following sequence after Power-On.  
But it is not able to accept Command input in Power off status, it has to take care that  
software reset is not perfectly alternative method of POR function.  
(1) CSB “L”“H”  
VDD
