TCAN285x-Q1 Automotive CAN FD SIC and LIN System Basis Chip (SBC) with Wake Inputs and High-side Switches

1 Features

AEC-Q100 qualified for automotive applications
Meets the requirements for CAN flexible data (FD) including the signal improvement capability (SIC) per ISO 11898-2:2024
Local interconnect network (LIN) physical layer specification ISO/DIS 17987–4:2024 compliant and conforms to SAEJ2602 recommended practice for LIN
Functional Safety Quality-Managed
Simplifies system power management with up to three regulators
- Low drop out (LDO) regulator supporting up to 250mA for 3.3V or 5V MCUs (VCC1)
- Short-to-battery protected 5V LDO regulator supporting up to 200mA externally (VCC2)
- Control of an external PNP transistor supporting up to 350mA at 1.8V, 2.5V, 3.3V or 5V (VEXCC)
Multiple methods to wake from sleep mode
- CAN and LIN bus wake up pattern (WUP)
- Optional, CAN selective wake up frame (WUF) capability (partial networking)
- Local wake up (LWU) via WAKE pins
  - Cyclic sensing wake up support with HSS4
- Digital wake up using the SW pin
Four high-side switches for loads up to 150mA
