DESCRIPTION

The L4969 is an integrated circuit containing 3 independent Voltage Regulators and a standard fault tolerant low speed CAN line interface in multipower BCD3S process.

It integrates all main local functions for automotive body electronic applications connected to a CAN bus.

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

■ LOW QUIESCENT CURRENT CONSUMPTION, LESS THAN 40µA IN SLEEP MODE

■ TWO VERY LOW DROP VOLTAGE REGULATORS 5V / 200mA AND 5V/200mA

■ SEPARATE VOLTAGE REGULATOR FOR CAN-TRANSCEIVER SUPPLY WITH LOW POWER SLEEP MODE

■ EFFICIENT UC SUPERVISION AND RESET LOGIC

■ 24 BIT SERIAL INTERFACE

■ AN UNPOWERED OR INSUFFICIENTLY SUPPLIED NODE DOES NOT DISTURB THE BUS LINES

■ VS VOLTAGE SENSE COMPARATOR

■ SUPPORTS TRANSMISSION WITH GROUNDSHIFT: SINGLE WIRE: 1.5V, DIFFERENTIAL: 3V
