Short functional description

The TLE 6368 G1 / SONIC is a multi voltage power supply system especially designed for automotive applications using a standard 12V / 24V battery as well as the new 42V powernet. The device is intended to supply 32 bit micro-controller systems which require different supply voltage rails such as 5V, 3.3V and 2.6V. The regulators for external sensors are also provided.

Features

• High efficiency regulator system

• Wide input voltage range from 5.5V to 60V

• Stand-by mode with low current consumption

• Suitable for standard 12V/24V and 42V PowerNets

• Step down converter as pre-regulator: 5.5V / 1.5A

• Step down slope control for lowest EME

• Switching loss minimization

• Three high current linear post-regulators with selectable output voltages:

5V / 800mA

3.3V or 2.6V / 500mA

3.3V or 2.6V / 350mA

• Six independent voltage trackers (followers): 5V / 17mA each

• Stand-by regulator with 1mA current capability

• Three independent undervoltage detection circuits (e.g. reset, early warning) for each linear post-regulator

• Power on reset functionality

• Tracker control and diagnosis by SPI

• All outputs protected against short-circuit

• Power-DSO-36 package
