3 Description

The TCAN843-Q1 is a high-speed Controller Area

Network (CAN) transceiver that meets the physical

layer requirements of the ISO 11898-2:2024 highspeed

CAN specification. The device supports both

classical CAN and CAN FD data rates up to 5

megabits per second (Mbps).

The TCAN843-Q1 allows for system-level reductions

in battery current consumption by selectively enabling

the various power supplies that may be present on

a system via the INH output pin. This allows a

low-current sleep state in which power is gated to

all system components except for the TCAN843-Q1,

while monitoring the CAN bus. When a wake-up event

is detected, the TCAN843-Q1 initiates system start-up

by driving INH high.
