SOLUTIONS
Analog Devices has launched several new members of
its digital isolation and iCoupler product families. The
new additions include automotive versions of its digital
isolation products, the ADuM5230 isolated half-bridge
driver, ADuM540x digitally isolated DC/DC converters and a
number of isolated transceiver products.
The ADuM120x, ADuM130x and ADuM140x families of iCoupler
digital isolators are now qualified to AEC-Q100 for use in under-
the-hood automotive applications. Available in eight- and 16-lead
SOIC packaging, the devices offer data rates up to 25Mbit/s, 3.0V
to 5.5V level translation and low power consumption. Applications
include hybrid vehicle functions such as battery monitoring, motor
drives, DC/AC inverters and electronic power steering. They can
also be employed in any vehicle type as an interface for sensor
clusters.
Analog Devices’ ADuM5230 is an isolated half-bridge gate driver
that provides independent and isolated high-side and low-side
outputs. Supplying 150mW of power, it contains an integrated DC/
DC converter, eliminating cost, space and performance difficulties
associated with external supply configurations.
Also integrating an isolated DC/DC converter for simpler system
design, the ADuM540x series of quad-channel digital isolators
provides four independent isolation channels in a variety of channel
configurations and data rates.
The ADM3251E is a high speed, single channel 2.5kV isolated
RS-232 transceiver that operates from a single power supply with
15kV ESD protection on the bus pins. Its high level of protection
suits it for operation in electrically harsh environments or where
cables are frequently being plugged and unplugged.
For RS485/422 applications, the ADM2482E/ADM2487E are
believed to be the industry’s fastest integrated 2.5kV isolated
data transceivers with transformer driver functionality. The devices
combine a three-channel 2.5kV UL and VDE certified isolator, a
three-state differential line driver and a differential input receiver
into a single package.
For RS-485/422 transceiver applications that require a higher
isolation rating, the ADM2484E offers 5kV UL and VDE certification
and enhanced ESD protection of ±15kV on the bus pins. The device
also has current-limiting and thermal shutdown features to protect
against output short circuits and situations where bus contention
might cause excessive power dissipation.
