5 TI’s CAN SIC Devices

TI has released CAN SIC devices compliant to both CiA 601-4 and ISO 11898-2:2024 Annex A, including the eight-pin TCAN1472-Q1 with standby mode support, and the 14-pin TCAN1473-Q1 and TCAN1473A-Q1 with sleep mode and a WAKE/INH capability. TI also offers the TCAN1473C-Q1 and TCAN1473AC-Q1, which are 14-pin CAN transceivers with sleep mode and a Wake/INH capability compliant to ISO 11898-2:2024 Set C, without including the additional CAN XL compatibility requirements outlined in Annex A. TI’s ISO 11898-2:2024 CAN SIC devices are shown below in Table 5-1.

The TCAN1472 is available in two variants: the TCAN1472 for 5V bus/logic levels and the TCAN1472V with 1.8V to 5V logic-level support. These devices have major benefits compared to competing devices in the market, as shown in Table 5-2.

Table 5-2 The TCAN1462 Compared to the Nearest Competing Device
Parameter Competing Device TCAN1472 End System Implication
Vio (logic supply) range 3V to 5.5V 1.7V to 5.5V TI is future ready for 1.8V logic I/O support
SIC timing Only meets with ±5% VCC With ±10% VCC TI does not need a tightly regulated supply to meet important SIC parameters required by standard
Minimum Vod of 1.5V Only meets with ±5% VCC With ±10% VCC
Bus fault protection –36V to 40V ±58V A high bus fault means more resistant to faults. Also, TI supports bus faults for 24V systems, enabling reuse across platforms
Electrostatic discharge (ESD) on bus pins ±6kV ±8kV Higher ESD protection
Small outline transistor-23 package No Yes TI offers a smaller footprint package option
