L4969UR-E

L4969URD-E

System voltage regulator with fault tolerant

low speed CAN transceiver

Features

■ Operating supply voltage 6 V to 28 V, transient

up to 40 V

■ Low quiescent current consumption, less than

40 µA in sleep mode

■ Two very low drop voltage regulators

5 V/200 mA

■ Separate voltage regulator for CAN transceiver

supply with low power sleep mode

■ Efficient microcontroller 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 1.5 V - differential: 3 V

Description

The L4969UR-E and L4969URD-E are integrated

circuits containing 3 independent voltage

regulators and a standard fault tolerant low speed

CAN line interface in multipower BCD3S process.

They integrate all main local functions for

automotive body electronic applications

connected to a CAN bus.
