ISO164x-Q1 Automotive, Hot-Swappable Bidirectional I2C Isolators with Enhanced

EMC

1 Features

3 Description

•

Qualified for Automotive Applications

AEC-Q100 Qualified With the Following Results:

– VDA320 Compliant

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

Ambient Operating Temperature

– Device HBM ESD Classification Level 3A

– Device CDM ESD Classification Level C6

Robust Isolated Bidirectional, I²C Compatible,

Communication

– ISO1640-Q1: Bidirectional SDA and SCL

communication

– Hot-Swappable SDA and SCL

Bidirectional data transfer up to 1.7 MHz Operation

Robust isolation barrier with enhanced EMC:

– >100-year projected lifetime at 450 V_RMS

working voltage (D-8) and 1500 V_RMSworking

voltage (DW-16)

The ISO1640-Q1 (ISO164x-Q1) device is a hot

swappable, low-power, bidirectional isolator that is

compatible with I²C interfaces. The ISO164x supports

UL 1577 isolation ratings of 5000 V_RMSin the 16-

DW package, and 3000 V_RMSin the 8-D package.

Each I²C isolation channel in this low emissions

device has a logic input and open drain output

separated by a double capacitive silicon dioxide

(SiO₂) insulation barrier. This family includes basic

and reinforced insulation devices certified by VDE,

UL, CSA, TUV and CQC. The ISO1640-Q1 has

two isolated bidirectional channels for clock and

data lines. ISO1640-Q1 integrates logic required

to support bidirectional channels, providing a much

simpler design and smaller footprint when compared

to optocoupler-based solutions.
