Free Delay Time Setting CMOS Voltage Detector IC Series
BD52xx series BD53xx series
●Key Specifications Detection voltage: ●General Description Rohm's BD52xx and BD53xx series are highly accurate, low current consumption Voltage Detector ICs with a capacitor-controlled time delay.
The line up includes BD52xx devices with N channel open drain output and BD53xx devices with CMOS output.
The devices are available for specific detection voltages ranging from 2.
3V to 6.
0V in increments of 0.
1V.
●Features Delay Time Controlled by external Capacitor Two output types (N channel open drain and CMOS output) Ultra-low current consumption Very small and low height package Package SSOP5 is similar to SOT-23-5(JEDEC) ●Typical Application Circuit
