Automotive CAN FD SIC system basis chip (SBC) with buck regulator and partial networking

The TCAN245x-Q1 is a family of system basis chips (SBC) that provide a control area network flexible data rate capable (CAN FD) transceiver that meets the physical layer requirements of ISO-11898:2-2024 including the SIC specification. The CAN FD transceiver supports data rates up to 8Mbps. The TCAN245x-Q1 integrates a buck regulator (VCC1) that can output either 3.3V or 5V, and provide up to 1A output current. The buck regulator integrates spread spectrum modulation to improve EMC performance. VCC2 LDO provides 5V output for loads up to 200mA. TCAN2451-Q1 supports Partial Networking by recognizing a selective wakeup frame (WUF)

The TCAN245x-Q1 includes features such as LIMP, four local wake inputs and four high side switches. The high side switch can be on/off, 10-bit PWM or timer controlled. Using the GFO pin, controlling an external CAN FD, LIN transceiver, CAN SBC or LIN SBC is possible. The WAKE pins can be configured for static sensing, cyclic sensing (with HSS4 pin) and pulse based for waking up. These devices provide EEPROM to store specific device configuration information: thus, avoiding extensive reprogramming after power fluctuations.
