Datasheet

Voltage Detector (Reset) IC Series for Automotive Application

Free Time Delay Setting

CMOS Voltage Detector (Reset) IC

BD52xxNVX-2C Series BD5320NVX-2C

General Description

Key Specifications

ROHM's Free Time Delay Setting CMOS Voltage

Detector ICs are highly accurate, with ultra-low current

consumption feature that uses CMOS process. Delay

time setting can be control by an external capacitor. The

lineup includes N-channel open drain output (BD52xx

NVX-2C) and CMOS output (BD5320NVX-2C). The

devices are available for specific detection voltage is 1.4

V, 1.6 V, 2.0 V, 2.6 V to 3.1 V (0.1 V step).

◼ Detection Voltage: 1.4 V, 1.6 V, 2.0 V, 2.6 V, 2.7 V

2.8 V, 2.9 V, 3.0 V, 3.1 V(Typ)

◼ Ultra-Low Current Consumption:

270 nA (Typ)

◼ Time Delay Accuracy:

±50 % (-40 °C to +125 °C,

CT pin capacitor ≥ 1 nF)

Special Characteristics

The time delay has ±50 % accuracy in the overall

operating temperature range of -40 °C to 125 °C.

◼ Detection Voltage Accuracy:

±3.0 %±12 mV (V_DET=1.4 V, 1.6 V)

±2.5 %(V_DET=2.0 V, 2.6 V to 3.1 V)

Features

◼ AEC-Q100 Qualified ^{(Note 1)}

◼ Nano Energy™

Package

SSON004R1010:

W(Typ) x D(Typ) x H(Max)

1.00 mm x 1.00 mm x 0.60 mm

◼ Delay Time Setting Controlled by External Capacitor

◼ Two output types (Nch open drain and CMOS

output)

◼ Miniature Surface-mount Package

(Note 1) Grade 1
