Automotive 100W infotainment display module reference design with functional safety capabilities<
PMP41085
概述
This reference design showcases the 100W automotive infotainment display module power reference design with cold crank, load dump and FuSa Capabilities.
The LM74900-Q1 is the first stage of the design playing a role of protection for negative input voltage, undervoltage, locked output, and overcurrent protection. The LM5152-Q1 is the second stage to function as pre-boost controller which can boost up to a specific voltage if battery voltage is low when starting up. The device supports battery voltages down to 4.2V. At the third stage, the design uses LMQ644A2-Q1, TPS62813-Q1, and TPS745-Q1 to provide the desired voltage to the subsystem like local dimming backlight, TCON, and SerDes.Lastly the design uses a voltage monitor and comparator to monitor each rail and to aid ISO 26262 system design to achieve the targeted ASIL.
