Standard CMOS
Voltage Detector IC
BD48□□G/FVE，BD49□□G/FVE Series
●General Description
ROHM's BD48□□G/FVE and BD49□□G/FVE series are highly accurate, low current consumption reset IC series. The lineup was
established with tow output types (Nch open drain and CMOS output) and detection voltages range from 2.3V to 6.0V in increments of 0.1V,
so that the series may be selected according the application at hand.
●Features
1）
Detection voltage: 2.3V to 6.0V (Typ.), 0.1V steps
2）
High accuracy detection voltage: ±1.0%
3）
Ultra-low current consumption: 0.8µA (Typ.)
4）
Nch open drain output (BD48□□G/FVE), CMOS output (BD49□□G/FVE)
5）
Compact packages VSOF5: BD48□□FVE, BD49□□FVE
●Applications
All electronic devices that use microcontrollers and logic circuits

Page 7: Operation Notes
Operation Notes 1 . Absolute maximum range Absolute Maximum Ratings are those values beyond which the life of a device may be destroyed. We cannot be defined the failure mode, such as short mode or open mode. Therefore a physical security countermeasure, like fuse, is to be given when a specific mode to be beyond absolute maximum ratings is considered. - Page 8 Any data, including, but not limited to application circuit diagrams and information, described herein are intended only as illustrations of such devices and not as the specifications for such devices.
