Free Time Delay Setting
CMOS Voltage Detector (Reset) IC
BD52xx-2C Series and BD53xx-2C Series
General Description ROHM's BD52xx-2C and BD53xx-2C series are highly accurate, low current consumption Voltage Detector ICs with a capacitor controlled time delay.
The lineup includes N-channel open drain output (BD52xx-2C) and CMOS output (BD53xx-2C) so that the users can select depending on the application.
The devices are available for specific detection voltage ranging from 0.
9V to 5.
0V with 0.
1V increment.
The time delay has ±50% accuracy in the overall operating temperature range of -40°C to 125°C.
Special Features AEC-Q100 Qualified (Note1) Nano Energy Delay Time Setting controlled by external capacitor Two output types (Nch open drain and CMOS output)
Very small, lightweight and thin package Package SSOP5 is similar to SOT-23-5 (JEDEC)
(Note1: Grade 1)
