Datasheet  
Voltage Detector IC Series  
Counter Timer Built-in  
CMOS Voltage Detector IC  
BU45Kxxxx, BU46Kxxxx, BU45Lxxxx, BU46Lxxxx series  
Key Specifications  
Detection voltage:  
General Description  
2.3V to 4.8V (Typ.)  
0.1V steps  
±1.0%  
ROHM’s BU45xxxxx and BU46xxxxx series are highly  
accurate, low current consumption voltage detector IC  
series. Because the counter timer delay circuit is built-in,  
an external capacitor for the delay time setting is  
unnecessary. Two output types are available (Nch open  
drain and CMOS output) and detection voltages range  
from 2.3V to 4.8V in increments of 0.1V with fixed delay  
time of 200ms and 400ms, that may be selected  
according to application.  
High accuracy detection voltage:  
Low current consumption:  
2.3µA (Typ.)  
-40°C to +105°C  
200ms  
Operating temperature range:  
Two internal, fixed delay time:  
400ms
