TJA1145

High-speed CAN transceiver for partial networking

2.2 Designed for automotive applications



8 kV ElectroStatic Discharge (ESD) protection, according to the Human Body Model

(HBM) on the CAN bus pins



6 kV ESD protection, according to IEC 61000-4-2 on pins BAT and WAKE and on the

CAN bus pins

 CAN bus pins short-circuit proof to

58 V

 Battery and CAN bus pins protected against transients according to ISO 7637-3, test

pulses 1, 2a, 3a and 3b.

 Suitable for use in 12 V and 24 V systems

 Available in SO14 and leadless HVSON14 package (3 mm

 4.5 mm) with improved

Automated Optical Inspection (AOI) capability

 AEC-Q100 qualified

 Dark green product (halogen free and Restriction of Hazardous Substances (RoHS)

compliant)

2.3 Advanced ECU power management system

 Very low-current Standby and Sleep modes, with full wake-up capability

 Entire node can be powered down via the inhibit output

 Remote wake-up capability via standard CAN wake-up pattern or via

ISO 11898-2:2016 compliant selective wake-up frame detection

 Local wake-up via the WAKE pin

 Wake-up source recognition

 Bit rates of 50 kbit/s, 100 kbit/s, 125 kbit/s, 250 kbit/s, 500 kbit/s and 1 Mbit/s

supported during selective wake-up'

 Local and/or remote wake-up can be disabled to reduce current consumption

 Transceiver disengages from the bus when the battery supply is removed

 VIO input allows for direct interfacing with 3.3 V to 5 V microcontrollers

2.4 Protection and diagnosis

 16-, 24- or 32-bit SPI for configuration, control and diagnosis

 Transmit Data (TXD) dominant time-out function with diagnosis

 Overtemperature warning and shut-down

 Undervoltage detection and recovery on pins VCC, VIO and BAT

 Cold start diagnosis (via bits PO and NMS)

 Advanced system and transceiver interrupt handling
