DESCRIPTION

The L9669 is an integrated circuit which contains a CAN physical line interface. It integrates all main local functions for automotive body electronic applications connected to a CAN bus.

■ FAULT TOLERANT DIFFERENTIAL CAN TRANSCEIVER

■ OPERATING SUPPLY VOLTAGE 6V TO 28V, TRANSIENTS UP TO 40V

■ LOW QUIESCENT CURRENT IN STANDBY MODE (100µA) AND SLEEP MODE (37µA)

■ ON CHIP DIAGNOSIS FOR ERRORS ON THE PHYSICAL BUSLINES WITH MICRO CONTROLLER INTERFACE

■ OPTIMIZED EMI BEHAVIOUR DUE TO LIMITED AND SYMMETRIC SLOPES OF CAN SIGNALS

■ AUTOMATIC SWITCHING TO SINGLE WIRE MODE UPON BUS FAILURES

■ TWO-EDGE SENSITIVE WAKE-UP PIN

■ SUPPORTS TRANSMISSION WITH GROUND SHIFT VOLTAGES: SINGLE WIRE: 1.5V DIFFERENTIAL WIRE: 3v

■ AN UNPOWERED NODE OR UNSUFFICIENT SUPPLIES DO NOT DISTURB THE BUS LINES
