Abstract
A set of peripheral chips for realizing hardware functions of a control device has at least two electronic units, which allow partitioning for the purpose of providing at least one basic functionality for a control device. This first and/or second electronic unit(s) may typically be configured as application-specific electronic switching circuit (ASIC).
Claims18
A set of peripheral chips for realizing hardware functions of a control device, comprising:
- at least two electronic units that ensure a partitioning so as to provide a basic functionality of the control device, the at least two electronic units including a first electronic unit and a second electronic unit,
- wherein:
- (a) the first electronic unit includes:
- a voltage supply having different output voltages;
- at least one transducer supply;
- a monitoring module;
- a driver for bi-directional serial interfaces;
- a CAN driver;
- a primary relay control;
- a primary relay output stage;
- a serial peripheral interface;
- and
- a stop/wake-up counter, and
- (b) the second electronic unit includes:
- a power output stage;
- at least one low-level signal output stage;
- and
- a voltage monitor.
