Figure 32. Line sensing function: internal block diagram and timing diagram
With reference to Figure 32 the following relationships can be established for the ON
(VinON) and OFF (VinOFF) thresholds of the input voltage:
which, solved for RH and RL, yield:
While the line undervoltage is active there is no PWM activity, thus the VCC voltage (if not
supplied by another source) continuously oscillates between the start-up and the UVLO
thresholds, as shown in the timing diagram of Figure 32.
As an additional measure of safety (e.g. in case the low-side resistor is open or missing, or
in non-power factor corrected systems in case of abnormally high input voltage) if the
