I'm building a device that will have STM32F750, and now thinking about stability in case if power or software will misbehave. As per topic - is it worth it to have an external voltage monitor and watchdog (Diodes Inc. APX823, for example)?
Obviously, STM32 has internal POR and watchdog (independent from main clock) - but will these two cover all the corner cases? Any suggestions?
Some technical details:
