CMOS Voltage Detector IC Series
BD52Exxx series BD53Exxx series
●General Description
●Key Specifications
¢ Detection voltage:
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
2.3V to 6.0V (Typ.)
0.1V steps
¢ High accuracy detection voltage:
¢ Ultra-low current consumption:
●Package
±1.0%
0.95µA (Typ.)
SSOP5:
2.90mm x 2.80mm x 1.25mm
●Applications
Circuits using microcontrollers or logic circuits that
require a reset.
¢ 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
