Voltage Detector IC Series
Free Delay Time Setting
CMOS Voltage Detector IC Series
BD52xx series BD53xx series
●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
VDD1
VDD2
●Key Specifications
Detection voltage:
2.3V to 6.0V (Typ.)
0.1V steps
High accuracy detection voltage:
±1.0%
Ultra-low current consumption:
0.95µA (Typ.)
●Package
SSOP5:
2.90mm x 2.80mm x 1.25mm
VSOF5:
1.60mm x 1.60mm x 0.60mm
●Applications
Circuits using microcontrollers or logic circuits that
require a reset.
