GENERAL DESCRIPTION
The ADM3056E is a 5.7 kV rms isolated controller area
network (CAN) physical layer transceiver. The ADM3056E fully
meets the CAN flexible data rate (CAN FD) CAN FD ISO 11898-
2:2016 requirements and is further capable of supporting data rates
as high as 12 Mbps.
Low propagation delays through the isolation support longer
bus cables. Slope control mode is available for the standard
CAN at low data rates. Standby mode can minimize power
consumption when the bus is idle, or if the node goes offline.
Silent mode allows the TXD input to be ignored for listen only
functionality.
The device employs Analog Devices, Inc., iCoupler® technology to
combine a highly robust 3-channel isolator and a CAN transceiver
into a single SOIC, surface-mount package. The ADM3056E
provides galvanic isolation between the CAN controller and
physical layer bus.
Dominant timeout functionality protects against bus lock up in
a fault condition, and current limiting and thermal shutdown
features protect against output short circuits. The device is fully
specified over the −40°C to +125°C industrial temperature range
and is available in a 16-lead, increased creepage, wide-body
SOIC package.
Safety and regulatory approvals (pending) for 5.7 kV rms isolation
voltage, 849 VPEAK working insulation voltage, 8 kV surge, and
8.3 mm creepage and clearance, ensure that the ADM3056E
meets isolation requirements for high voltage applications.
