Example of Over-voltage Protection Circuit.
Generally, in constant-voltage power supply circuit, output voltage will become higher than the specified value (over-
voltage state) in case of any failures or PC board solderability defects. To minimize the damage caused by this over
voltage, we recommend setting an over-voltage protection circuit.
In designing, the following confirmations are necessary in actual circuit.
1) How the over-voltage protection circuit operates and its effects.
2) Is there any malfunction due to ambient temperature change of each device or exogenous noises?
Over-voltage Protection Circuit Example
Example of Over-voltage Protection Circuit
The thyristor will operate when it accept an over-voltage (VOUT) signal, then the fuse is melted and the input power is cut
off, then the operation of IC1 is stopped.
