BD46312G
3.1V, Fixed Delay (200msec), CMOS Output Type, High Accuracy Voltage Detector

ROHM's BD45xxxG and BD46xxxG series of reset ICs utilize CMOS processes for low current consumption and high accuracy. The built-in counter timer delay circuit eliminates the need to set the delay time via external capacitor. The extensive lineup includes both Nch Open Drain and CMOS output types in a wide range of detection voltages (from 2.3V to 4.8V, in 0.1V steps), enabling selection of the ideal solution based on customer requirements. A total of 156 models are offered, classified by delay time. In addition, the entire series is of course both lead-free and RoHS-compliant.
