SLLSF83A May 2021 – November 2021 TCAN11623-Q1 , TCAN11625-Q1
PRODUCTION DATA
The TCAN1162x-Q1 are high-speed controller area network (CAN) system basis chips (SBC) that meet the physical layer requirements of the ISO 11898-2:2016 high-speed CAN specification. The TCAN1162x-Q1 supports both classical CAN and CAN FD networks up to 8 megabits per second (Mbps).
Both the TCAN11623-Q1 and TCAN11625-Q1 support a wide input supply range and integrates some form of an LDO output. The TCAN11625-Q1 has a 5-V LDO output (VCCOUT) which supplies the CAN transceiver voltage internally as well as additional current externally. The TCAN11623-Q1 has a 3.3-V LDO output (VLDO3), supplied from the 5-V LDO, supporting external loads.
The TCAN1162x-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 TCAN1162x-Q1, while monitoring the CAN bus. When a wake-up event is detected, the TCAN1162x-Q1 initiates system start-up by driving INH high.

This allows an ultra-low-current sleep state in which power is gated to all system components except for the TCAN1162x-Q1, which remains in a low-power state while monitoring the CAN bus. When a wake-up event is detected, the TCAN1162x-Q1 initiates node start-up by driving INH high.
The TCAN1162x-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 TCAN1162x-Q1 includes internal logic level translation via the VIO terminal to allow for interfacing directly to 1.8-V, 2.5-V, 3.3-V, or 5-V 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 ±58-V.
The TCAN1162x-Q1 allows for system-level reductions in battery current consumption by selectively enabling the various power supplies that may be present on a node via the INH output pin. This allows an ultra-low-current sleep state in which power is gated to all system components except for the TCAN1162x-Q1, which remains in a low-power state while monitoring the CAN bus. When a wake-up pattern is detected on the bus or when a local wake-up is requested via the WAKE input, the TCAN1162x-Q1 initiates node start-up by driving INH high.
