7. Verification Status (Sample)

| Test | Result | Notes | |------|--------|-------| | Power-on reset timing | Pass | 5 ms to output ready | | OCP at 25°C | Fail | Trip @ 15 A instead of 12 A (due to ISR delay) | | I²C register read/write | Pass | 400 kHz operation | | Thermal shutdown at 125°C | Pass | Interrupt-driven, clean halt | | Brown-out recovery | Pass | Resumes normal operation | Power on the device

3. Strengths

• Robust Initialization: All registers cleared to safe defaults before enabling output drivers.
• Watchdog Integration: External watchdog fed correctly inside main loop; failure causes safe shutdown.
• Diagnostic Logging: Last 5 fault events (overvoltage, overtemp, short-circuit) stored in non-volatile memory.
• Low Power Mode: Idle current < 50 µA achieved by disabling non-critical peripherals.
