LIN core system basis chip
2. Features and benefits
2.1 General
Contains LIN ECU functions:
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
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
LIN bus pin and the wake pins
±6 kV ElectroStatic Discharge (ESD) protection IEC 61000-4-2 on the LIN bus pin
and the wake pins
±58 V short-circuit proof LIN bus pin
Battery and LIN bus pins are protected against transients in accordance with
ISO 7637-3
Small 6.1 mm × 11 mm HTSSOP32 package with low thermal resistance
Pb-free; RoHS and dark green compliant
2.2 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
2.3 Power management
Wake-up via 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
Output signal (WBIAS) to bias the wake pins, selectable sampling time of 16 ms or
64 ms
Standby mode with very low standby current and full wake-up capability; V1 active to
maintain supply to the microcontroller
Sleep mode with very low sleep current and full wake-up capability
2.4 Control and Diagnostic features
Safe and predictable behavior under all conditions
Programmable watchdog with independent clock source
