3 Description
The ISO652x-Q1 devices are high-performance,
dual-channel functional isolators designed for cost
sensitive, space constrained applications that require
isolation for non-safety applications. The isolation
barrier supports a working voltage of 450VRMS and
transient over voltages of 1000VDC.
The ISO652x-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.
ISO6520-Q1 has two isolation channels with both
channels in the same direction. ISO6521-Q1 has two
isolation channels with one 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.
These devices help prevent ground loops and noise
currents between mixed voltage domain systems
on data buses, such as CAN and LIN, from
causing data corruption. Through chip design and
layout techniques, the electromagnetic compatibility
of the ISO652x-Q1 devices have been significantly
enhanced to ease system-level ESD and emissions
compliance.
