Infotainment in Cabin

/ Enabling More than Just the GPS

/ Application Considerations

Power staging and reverse battery protection are just a few of the factors that go into designing an infotainment system. Engineers should also consider:

• Overvoltage protection - we recommend including measures to address overvoltage that could cause safety issues or malfunctions 
• Transient protection - TVS devices are typically used to suppress transients and voltage spikes that could damage electronic systems
  
• ESD protection - measures must be in place to handle electrostatic discharge when designing circuits and systems
• Power staging - utilizing power staging ensures the right voltage and current levels are used at the right time in various functions within the infotainment system 
• Electromagnetic capability - EMI from other devices could interfere with the infotainment system and should be designed with measures to protect in-vehicle systems  
• High-current capability - infotainment systems must be able to handle enough power to run multiple systems at once, including some that require significant energy
• Component size - small, lightweight components are ideal for infotainment systems to help reduce impact on vehicle performance while leaving room for other necessary electronic elements within the cabin
• Reliability in harsh conditions - when safety and communication with the driver are concerned, there’s no room for component failure amid extreme conditions 
• Applicable industry standards - infotainment components should meet all industry requirements and standards, including AEC-Q101
