Automotive CAN-FD transceiver with integrated 5-V supply

The TCAN1162-Q1 is a high-speed Controller Area Network (CAN) transceiver that meets the

physical layer requirements of the ISO 11898-2:2016 high-speed CAN specification. The TCAN1162-Q1 supports both classical CAN and CAN FD networks up to 8 megabits per

second (Mbps).

The TCAN1162-Q1 integrates a 5V LDO with a wide input operating range which provides the

CAN transceiver voltage thereby eliminating the need for the 5V supply to be supplied from

an external voltage source.

The TCAN1162-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 an ultra-low-current sleep state where power is gated to all system

components except for the TCAN1162-Q1, while monitoring the CAN bus. When a

wake-up event is detected, the TCAN1162-Q1 initiates system start-up by driving

INH high.

The TCAN1162-Q1 supports an ultra low-power standby mode where the high-speed

transmitter and normal receiver are switched off and a low-power wake-up receiver enables

remote wake-up via the ISO 11898-2:2016 defined wake-up pattern (WUP).

The TCAN1162-Q1 includes internal logic level translation via the VIO

terminal to allow for interfacing directly to 1.8V, 2.5V, 3.3V, or 5V controllers. The

transceiver includes many protection and diagnostic features including undervoltage

detection, over voltage detection, thermal shutdown (TSD), driver dominant timeout (TXD

DTO), and bus fault protection up to ±58V.
