TIDA-01369 Wide VIN Supervised Multi-rail Power Supply with Low Voltage MCU Core Rail Reference Design | TI.com
TIDA-01369: The TIDA-01369 reference design is a power supply designed for providing power to lock-step dual-core microcontrollers (MCUs) with functional safety architectures, regulating down from an automotive battery or industrial DC supply in a single stage. MCUs from multiple vendors are supported by the design. The core and I/O rails for the MCU are supervised; if a fault condition occurs, the MCU is disabled by hardware RESET output signals and the latching fault condition is reported to the MCU after normal operation is resumed. The reference design emphasizes the complementary features of three products from TI: the TPS653850-Q1 power management IC (PMIC), the TPS57160-Q1 asynchronous DC-DC buck converter, and the TPS3700-Q1 overvoltage and undervoltage supervisor.
