Datasheet
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 reset IC series with
a built-in delay circuit. The lineup was established with
tow output types (Nch open drain and CMOS output)
and detection voltages range from 2.3V to 6.0V in
increments of 0.1V, so that the series may be selected
according the application at hand.
●Features
Free delay time setting by external capacitor
Two output types (Nch open drain and CMOS output)
Ultra-low current consumption
Very small and low height package
●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 1.15mm
VSOF5: 1.60mm x 1.60mm x 0.60mm
●Applications
All electronic devices that use micro controllers and logic
circuits
●Typical A pplication Circuit
