TECHNICAL NOTE
Voltage Detector IC Series
Counter Timer Built-in
CMOS Voltage Detector IC
BD45□□□G, BD46□□□G series
●
General Description
ROHM’s BD45□□□G and BD46□□□G series are highly accurate, low current consumption reset IC series. Because the counter timer
delay circuit is built into those series, an external capacitor for the delay time setting is unnecessary. The lineup was established with tow
output types (Nch open drain and CMOS output) and detection voltages range from 2.3V to 4.8V in increments of 0.1V, so that the series may
be selected according the application at hand.
●
Features
1）
Detection voltage: 2.3V to 4.8V (Typ.), 0.1V steps
2）
High accuracy detection voltage: ±1.0%
3）
Ultra-low current consumption: 0.85μA (Typ.)
4）
Three internal, fixed delay time: 50 msec, 100 msec and 200 msec
5）
Nch open drain output (BD45□□□G), CMOS output (BD46□□□G)
6）
SSOP5 compact surface mount packages
7）
Operating temperature range: -40℃ to +105℃
●
Applications
All electronic devices that use microcontrollers and logic circuits
