The TCAN29xx-Q1 is a family of system basis chips (SBC) that provide a control area network flexible data rate capable (CAN FD) transceiver. The TCAN2955-Q1 and TCAN2957-Q1 includes a local interconnect network (LIN) transceiver. The CAN FD transceiver supports data rates up to 8Mbps while the LIN transceiver supports fast mode data rates up to 200kbps. The VCC1 LDO provides 3.3V or 5V ±2% with up to 250mA of current and determines the digital IO logic values. If more current is needed an external PNP transistor can be used to support up to 350mA and voltages of 1.8V, 2.5V, 3.3V or 5V. VCC2 LDO provides 5V up to 100mA.

The TCAN29xx-Q1 includes features such as LIMP, upto five local wake inputs (four high-voltage inputs and one digital input) and four high side switches. The high side switch can be on/off, 10-bit PWM or timer controlled. Using the GFO pin it is possible to control an external CAN FD, LIN transceiver, CAN SBC or LIN SBC. The WAKE pins can be configured for static sensing or cyclic sensing . WAKE1 and WAKE2 can be alternatively configured to have an internal switch between the pins to enable external VBAT monitoring. WAKE3 can be configured as a direct drive control pin for any combinations of high-side switches.
