15.7 Power supply diagnostics
15.7.1 Power good output
“ Power good ” output is High (3,3V) when all output voltages are present. The “ Power good ” output will toggle
Low (0V) at least 5ms before 12V outputs decrease below specified level at an AC input voltage interrupt or
when the PSU goes into standby mode.
15.7.2 AC input voltage monitoring
The AC input voltage is monitored and a value representing the level is available on channel VIN2 on the I2C
A/D ADC128D818CIMT on the I2C address ox1D. (7-bit address)
This is used to decide if the projector is operating on 115V AC or 230V AC range.
15.7.3 Power supply ID
The power supply ID is available for reading from an I/O-expander PCA9555BS on I2C address 0x27 (7-bit
address).
15.7.4 Temperature monitoring
The temperature on the PFC converter heatsink is monitored and a value representing the level is available on
channel VIN1 on the I2C A/D ADC128D818CIMT on the I2C address ox1D. (7-bit address)
15.7.5 Consumption monitoring
The current consumption on the 12V converter is monitored and a value representing the level is available on
channel VIN0 on the I2C A/D ADC128D818CIMT on the I2C address ox1D. (7-bit address)
This current is the sum of consumption on 12V-1, 12V-2 and 12V-3 output
