...
- Verify the 48V outputs can be enabled and disabled via N-CH FET (can draw load from the output when enabled, can’t otherwise)
- Verify the analog output of the amplifier matches expectations
5V Power:
- Power onboard + touch test, verify components and the board itself does not get too hot
- 5V_1
- 5V_2
- Verify all ICs, details, LEDs, etc. are powered on successfully. Communicate with all peripherals
- 5V_1
- 5V_2
STM:
- Verify the enable pins can be driven high and low (PC14, PC11, PB9, PD2)
- Verify the STM can read the state of the OC pins accurately (PC13, PC12, PC10, PB8)
- Verify the analog reads of both of the 5V rails (PB7, PC15)
- Both of the pins for this are not analog capable, but was able to read from a peripheral
Electrical
- Verify enable condition on all 4 switches (can draw load from the output when enabled, can’t otherwise)
- Verify output current limit (2.4A)
- The current limit is actually 2A not 2.4A
- Verify the OC pin goes low in this condition
...
- Verify the 17V output can be enabled and disabled vis N-CH FET (can draw load from the output when enabled, can’t otherwise)
- N-CH footprint has source and drain pins reversed
- Verify the analog output of the amplifier matches expectations
- Verify the TVS diode function protects against an oversimplification of signal
