Bus-Fault Protection of –27 V to 40 V
Dominant Time-Out Function
AEC-Q100.(1)
As a CAN transceiver, this device provides differential
transmit capability to the bus and differential receive
capability to a CAN controller at signaling rates up to
1 megabit per second (Mbps)(2).
Power-Up/Down Glitch-Free Bus Inputs and
Outputs
–
–
High Input Impedance with Low VCC
Designed for operation is especially harsh
environments, the HVD1050 features cross-wire,
over-voltage and loss of ground protection from -27 V
to 40V, over-temperature shut down, a -12 V to 12 V
common-mode range, and will withstand voltage
transients from -200 V to 200 V according to ISO
7637.
