UJA1075
High-speed CAN/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 LIN transceiver
‹ 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 transceiver
„ LIN 2.1 compliant LIN transceiver
„ 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
