●
Pin 3: reset pin
Figure 20.
Pin usage and reset circuit
●
Pin 4: ADC channel 0 analog input, to measure the main DC bus voltage (VBUS). A
resistor partition is used to obtain, starting from a +400 V of bus a maximum of 5 V,
compatible with the MCU voltage input, see Figure 23.
Figure 21.
Vbus measurement circuit
●
Pin 5: ADC analog input 1: not used
●
Pin 6: ADC analog input 2: This pin is used to measure the lamp voltage. In Figure 23
there are two nets. The first one is a partitioning circuit composed of resistors R118-
R114, the other one composed of R117-R116. The voltage across the capacitors C114
and C115 is used as input of U4a to obtain a signal compatible with the MCU input.
