BD5227NVX-2C
Free Time Delay Setting CMOS Voltage Detector (Reset) IC

ROHM's Free Time Delay Setting CMOS Voltage Detector ICs are highly accurate, with ultra-low current consumption feature that uses CMOS process. Delay time setting can be control by an external capacitor. The lineup includes N-channel open drain output BD5227NVX-2C. The devices are available for specific detection voltage ranging from 2.6 V to 3.1 V with 0.1 V increment. The time delay has ±50 % accuracy in the overall operating temperature range of -40 °C to 125 °C.
