Datasheet

Voltage Detector (Reset) IC Series for Automotive Application

Free Time Delay Setting

CMOS Voltage Detector (Reset) IC

BD52xx-2M Series and BD53xx-2M Series

General Description

Key Specifications

ROHM's BD52xx-2M and BD53xx-2M series are highly

accurate, low current consumption Voltage Detector

ICs with a capacitor controlled time delay. The lineup

includes N-channel open drain output (BD52xx-2M)

and CMOS output (BD53xx-2M) so that the users can

select depending on the application. The devices are

available for specific detection voltage ranging from

0.9V to 5.0V with 0.1V increment.

 Detection Voltage:

0.9V to 5.0V (Typ.)

0.1V step

 Ultra-Low Current Consumption:

270nA (Typ.)

 Time Delay Accuracy:

±30% (-40°C to +105°C, )

(CT pin capacitor ≥ 1nF)

Special Characteristics

 Detection Voltage Accuracy:

The time delay has ±30% accuracy in the overall

operating temperature range of -40°C to 105°C.

±2.0%±12mV (V_DET=0.9V to 1.6V)

±2.5% (V_DET=1.7V to 5.0V)

Special Features

 AEC-Q100 Qualified ^(Note1)

Package

 Nano Energy

SSOP5:

W(typ) x D(typ) x H(max)

 Delay Time Setting controlled by external capacitor

 Two output types (Nch open drain and CMOS output)

 Very small, lightweight and thin package

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

(Note1: Grade 1)

2.90mm x 2.80mm x 1.25mm

Application

 Automotive (audio system, navigation system, etc.)
