High-speed CAN/dual LIN core system basis chip

2. Features and benefits

2.1 General

„ Contains a full set of CAN and LIN ECU functions:

‹ CAN transceiver and two LIN transceivers

‹ Scalable 3.3 V or 5 V voltage regulator delivering up to 250 mA for a

microcontroller and peripheral circuitry; an external PNP transistor can be

connected for better heat distribution over the PCB

‹ Separate voltage regulator for the CAN transceiver (5 V)

‹ Watchdog with Window and Timeout modes and on-chip oscillator

‹ Serial Peripheral Interface (SPI) for communicating with the microcontroller

‹ ECU power management system

„ Designed for automotive applications:

‹ Excellent ElectroMagnetic Compatibility (EMC) performance

‹ ±8 kV ElectroStatic Discharge (ESD) protection Human Body Model (HBM) on the

CAN/LIN bus pins and the WAKE pins

‹ ±6 kV ElectroStatic Discharge (ESD) protection IEC 61000-4-2 on the CAN/LIN bus

pins and the WAKE pins

‹ ±58 V short-circuit proof CAN/LIN bus pins

‹ Battery and CAN/LIN bus pins are protected against transients in accordance with

ISO 7637-3

„ Supports remote flash programming via the CAN bus

„ Small 6.1 mm × 11 mm HTSSOP32 package with low thermal resistance

„ Pb-free; RoHS and dark green compliant

2.2 CAN transceiver

„ ISO 11898-2 and ISO 11898-5 compliant high-speed CAN transceiver

„ Dedicated low dropout voltage regulator for the CAN bus:

‹ Independent of the microcontroller supply

‹ Significantly improves EMC performance

„ Bus connections are truly floating when power is off

„ SPLIT output pin for stabilizing the recessive bus level

2.3 LIN transceivers

„ 2 × LIN 2.1 compliant LIN transceivers

„ Compliant with SAE J2602

„ Downward compatible with LIN 2.0 and LIN 1.3

„ Low slope mode for optimized EMC performance

„ Integrated LIN termination diode at pin DLIN

2.4 Power management

„ Wake-up via CAN, LIN or local WAKE pins with wake-up source detection

„ 2 WAKE pins:

‹ WAKE1 and WAKE2 inputs can be switched off to reduce current flow
