Strata Enabled USB Automotive 2-Port 100W Source

The Strata based Dual 100W USB PD Automotive Charging System demonstratesonsemi's broad portfolio of USB PD and Power Solutions, including the FUSB302 Type-C & PD Port Controller, the FUSB252 HV Protection Switch, and the NCV81599 4-switch buck-boost controller. 

Additionally, the Strata software also provides full control over the system and allows the user to experiment with various fault and foldback features, change power profiles on each port, and monitor telemetry while charging various load devices. Design collateral such as schematics, PCB layout, test reports, etc. are supplied in the same Strata interface to ease evaluation.
