ISO672x-Q1 General Purpose Reinforced and Basic Dual-Channel Automotive Digital

Isolators with Robust EMC

1 Features

3 Description

•

Functional Safety-Capable

The ISO672x-Q1 devices are high-performance, dual-

channel digital isolators ideal for cost sensitive

applications requiring up to 5000 V_RMS(DWV

package) and 3000 V_RMS(D package) isolation

ratings per UL 1577. These devices are also certified

by VDE, TUV, CSA, and CQC.

– Documentation available to aid functional safety

system design: ISO6720-Q1, ISO6721-Q1

AEC-Q100 qualified with the following results:

– Device temperature Grade 1: –40°C to +125°C

ambient operating temperature range

Meets VDA320 isolation requirements

50-Mbps data rate

•

The

ISO672x-Q1

devices

provide

high

electromagnetic immunity and low emissions at

low power consumption, while isolating CMOS or

LVCMOS digital I/Os. Each isolation channel has a

logic input and output buffer separated by TI's double

capacitive silicon dioxide (SiO₂) insulation barrier. The

ISO6720-Q1 device has 2 isolation channels with

both channels in the same direction. The ISO6721-Q1

device has 2 isolation channels with 1 channel in

each direction. In the event of input power or signal

loss, the default output is high for devices without

suffix F and low for devices with suffix F. See Device

Functional Modes section for further details.

Robust isolation barrier:

– High lifetime at 1060 V_RMSworking voltage

– Up to 5000 V_RMSisolation rating

– ±75 kV/μs typical CMTI

Wide supply range: 1.71 V to 1.89 V and 2.25 V to

5.5 V

1.71-V to 5.5-V level translation

Default output High (ISO672x-Q1) and Low

(ISO672xF-Q1) Options

1.8 mA per channel typical at 1 Mbps

Low propagation delay: 11 ns typical

Robust electromagnetic compatibility (EMC)

– System-Level ESD, EFT, and surge immunity

– ±8 kV IEC 61000-4-2 contact discharge

protection across isolation barrier

– Low emissions

Narrow-SOIC (D-8) and Wide-SOIC (DWV-8)
