5 TI’s CAN SIC Devices

TI has released two CAN SIC devices: the eight-pin TCAN1462 with standby mode support, which is pin-to-pin compatible with traditional eight-pin CAN transceivers; and the 14-pin TCAN1463 with sleep mode and a WAKE/INH capability, which is pin-to-pin compatible with traditional 14-pin CAN transceivers.

The TCAN1462 is available in two variants: the TCAN1462 for 5-V bus/logic levels and the TCAN1462V with 1.8- to 5-V logic-level support. These devices have major benefits compared to competing devices in the market, as shown in Table 5-1.

Table 5-1 The TCAN1462 Compared to it's Nearest Competing Device
Parameter Competing Device TCAN1462 End System Implication
Vio (logic supply) range 3 V to 5.5 V 1.71 V to 5.5 V TI is future ready for 1.8-V 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 1.5 V Only meets with ±5% VCC With ±10% VCC
Bus fault protection –36 V to 40 V ±58 V A high bus fault means more resistant to faults. Also, TI supports bus faults for 24-V systems, enabling reuse across platforms
Electrostatic discharge (ESD) on bus pins 6 kV ±8 kV Higher ESD protection
Small outline transistor-23 package No Yes TI offers a smaller footprint package option
