CMOS Voltage Detector IC Series

BD52Exxx series BD53Exxx series

●General Description

Rohm's BD52Exxx and BD53Exxx series are highly accurate, low current consumption Voltage Detector ICs with a capacitor controlled time delay. The line up includes BD52Exxx devices with N-channel open drain output and BD53Exxx 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, lightweight and thin package

Package SSOP5 is similar to SOT-23-5(JEDEC)
