Vehicle Control Unit (VCU)

Описание:
Reverse polarity is standard protection required in an automotive environment. When battery cables are detached and reconnected there is a probability of connecting the wires to wrong terminals of the battery. This mistake could damage the components in Electronic Control Units (ECU). To avoid damage to the ECU there is a need for reverse polarity protection. Schotky diodes could be used but will have a constantly high power loss. This reference design uses the LM5050-Q1 along with n-channel mosfet to provide reverse polarity protection and reduce the power dissipation.
Возможности:

Reverse polarity protection for 12V/24V/48V Oring controller to connect multiple batteries Improves system efficiency and very low quiescent current Replaces the Schottky diode and reduces the power dissipation ISO7637-2 and ISO16750-2 compliant

Automotive battery power supply lines are prone to transients while running the system. Typical protections required are overvoltage, overload, reverse polarity, and jump start. During the life of a car, the alternator may be replaced with a non-OEM part. The after-market alternator may have different or no load dump protection, which could lead to damaging the electronic control unit (ECU). This TI Design provides protection to handle these potential unsuppressed load dump pulses (12 V and 24 V) with hardware control. Class A operation may be attained during unsuppressed load dump pulses.
Возможности:

Wide input protection voltage range Scalable to multiple battery topologies (12V, 24V, 48V) Configurable options to support Class A operation during unsuppressed load dump pulses Compliance to ISO7637-2, ISO16750-2

The TIDA-01255 design is built for isolated CAN communication, which is widely used in automotive environments. In hybrid and electric vehicles (HEV/EVs), a complete high-voltage network is floating with respect to the chassis ground. Isolation is required for the power and communication channels interfaced between floating high- to low-voltage systems. The TIDA-01255 design supports applications with a simple isolated transformer driver to transfer power. This TI Design has a low-transmission delay, which reduces the loop delay and supports higher baud rates of the CAN.
Возможности:

Flexible high-speed CAN communication Low loop delay (typically 136 ηs) to support high-speed arbitration rates 750-mW power transfer with 3-kV isolation ±70-V bus fault protection Compliant with ISO 11898-2 CAN standard

The TIDA-01425is a subsystem reference design for automotive gateways focused on increasing bandwidth and processing power in gateway applications. The design implements ethernet physical layer transceivers (PHYs) for increased bandwidth along with an automotive processor for greater processing capabilities allowing automotive gateways to pass more data at higher speeds. Furthermore, the reference design offers a starting point for a full automotive gateway design with a full power tree, CAN PHYs, and components selected with automotive requirements and emission specifications in mind to simplify the design process.
Возможности:

Processor based system 100BASE-TX and CAN PHYs Operates off automotive battery Designed to operate through cold crank, jump start, and load dump Reduced EMI power stages Reverse battery protection
