L4969URTR-E Datasheet, PDF (1/46 Pages) STMicroelectronics – System voltage regulator with fault tolerant low speed CAN transceiver

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
■ V_S 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.
