This reference design implements a safe-power supply for powering up microcontrollers in an architecture featuring two MCUs. The design has several protection features including overvoltage protection and short circuit protection to prevent the MCUs from getting damaged. The DC/DCs, LMR36515 and LMR36015 convert the 5-V and 12-V rail into 3.3 V, which is monitored by the TPS3703 and TPS3702 voltage monitors respectively.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
