Voltage Detector IC Series

The ROHM voltage detector IC series are reset IC with highly accurate detection voltage of ±1% , low current consumption, small thin packages and wide range of detection voltage. They can be used for every kind of application equipped with controllers such as micro controllers, CPU or DSP.
In the ROHM voltage detector IC series, both CMOS and open drain output are available, therefore output of reset signal can be selected for connected power supply. Default SSOP packages are pin-compatible and function-compatible, so they can be used as replacement for existing IC. Besides, a lineup of very small and thin package makes compact implementation near micro controllers possible. All lineups are Pb-free, and meet RoHS.
