Power, reliability and safety
Design robust embedded products.
📖 Key ideas
- Low-power modes (sleep, deep sleep) extend battery life.
- Brown-out detection resets on low voltage.
- Watchdog timers recover from hangs.
- EMC, ESD protection and good PCB layout improve reliability.
- Safety standards: ISO 26262 (automotive), IEC 61508, IEC 62304 (medical).
💡 Real-life example: Reliability design is a hospital generator plan: if something fails, the system recovers safely.
