Voltage Detector IC Series
Counter Timer Built-in
CMOS Voltage Detector IC
BD45□□□G, BD46□□□G series
No.09006ECT06
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%
4) Operating temperature range: -40°C to +105°C
6) SSOP5 compact surface mount packages
3) Ultra-low current consumption: 0.85µA (Typ.)
5) Three internal, fixed delay time: 50ms, 100ms and 200ms
7) Nch open drain output (BD45□□□G), CMOS output (BD46□□□G)
Applications
All electronic devices that use microcontrollers and logic circuits
