CMOS Voltage Detector IC Series

BD52xx series BD53xx series

●General Description

●Key Specifications

¢ Detection voltage:

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

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

VSOF5:

1.60mm x 1.60mm x 0.60mm

¢ Delay Time Controlled by external Capacitor

¢ Two output types (N channel open drain and CMOS

output)

●Applications

Circuits using microcontrollers or logic circuits that

require a reset.

¢ Ultra-low current consumption

¢ Very small and low height package

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