Description

AZKN1044T is a ±15kV IEC 61000-4-2 protected

Controller Area Network (CAN) transceiver IC. It

serves as an interface between a CAN protocol

controller (MCU) and the physical two-wire CAN bus.

This device operates at 5V power supply and is fully

compliant with ISO 11898-2:2016 standard for CAN

FD application. The data rate of both driver and

receiver is up to 5Mbps to support the high-speed

application of the CAN FD.

AZKN1044T has the capabilities of both the ±40V

common mode range of the receiver and the low EME

of the transmitter, which has been patented as the

Amazing's intellectual property. Moreover, the

whole-chip design of the AZKN1044T can sustain

±2kV EFT coupling under communication.

AZKN1044T is a robust CAN transceiver, which

features ±70V fault protection to sustain the DC short

voltage on the bus pins. Moreover, AZKN1044T has

±100V surge protection immunity to avoid the possible

damage from the EOS events. In addition, the

whole-chip ESD protection immunity of AZKN1044T

can sustain HBM ±6kV, MM ±400V and CDM ±800V,

which is satisfied with the AEC-Q100 specifications to

overcome the ESD zapping under the worst

manufacture environment.
