Description for the TCAN1144-Q1
The TCAN114x-Q1 is a family of enhanced high-speed, CAN FD transceivers supporting data rates up to 5 Mbps. The devices are configured using serial peripheral interface (SPI) for access to full functionality. The TCAN114x-Q1 supports nominal processor IO voltages from 1.8 V to 5 V by applying the appropriate voltage to the VIO pin, allowing lower power processors to be used.
The TCAN1145-Q1 and TCAN1146-Q1 transceivers support selective wake (being able to wake-up based on WUF identification). This feature enables systems to implement partial networking and operate with a reduced number of nodes in an active state while the remaining nodes are in a low-power sleep mode). The transceivers and selective wake function meet the specifications of the ISO 11898-2:2016 standard.
The TCAN1144-Q1 and TCAN1146-Q1 are full featured devices supporting watchdog and advanced bus diagnostics. For ease of debug, the advanced bus fault diagnostics and communication feature can be used to determine specific bus faults.
The TCAN114x-Q1 is a family of enhanced high-speed CAN FD transceivers that are register compatible enabling system designers the flexibility to implement features needed without hardware modifications and with minimal software changes. The TCAN1144-Q1 and TCAN1146-Q1 inhibit (INH) pin can be used to either enable node power or be configured as a limp home pin when a watchdog error takes place.

Select a carrier option
NEW - You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.
A custom reel
is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.
Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.TI often ships
devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
