Power Supply Protection
D-Board
Figure 39
Regulation and protection of the power supply are handled via the following
inputs:
1) The voltage feedback is applied to pin 9 of IC801 via the opto-coupler IC,
IC811.
2) Current feedback is applied via pin 4 of IC801.
3) Over Voltage Protection (OVP) is provided via pin 8 of IC801.
4) Under Voltage Lock Out (UVLO) is sensed at pin 7 of IC801.
