The TCAN285x-Q1 is a family of system basis chips (SBC) that provide a control area network flexible data rate capable (CAN FD) SICtransceiver that supports selective wake. The TCAN2857-Q1 includes a local interconnect network (LIN) transceiver. The CAN FD SICtransceiver 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 levels. 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 200mA.
The TCAN285x-Q1 includes features such as LIMP, three local wake inputs and four high side switches. The high side switch can be on/off, 10-bit PWM or timer controlled. Controlling an external CAN FD, LIN transceiver, CAN SBC or LIN SBC is possible using the GFO pin. 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. WAKE1 and WAKE2 can enable an internal switch between pins to enable external VBAT monitoring. WAKE3 can be configured as a direct drive control pin for any combinations of high-side switches when cyclic sensing wake is enabled.
