CIRCUIT FOR PROTECTING A SEMICONDUCTOR DEVICE FROM VOLTAGE PRODUCED BY DISCHARGES OF STATIC ELECTRICITY

摘要

A protection circuit (10) for protecting a semiconductor device (11) includes a plurality of fuses (15a-15k) and a switching device (16) connected in parallel to the input capacitor (14) of the semiconductor device (11). The fuses (15a-15k) protect the device (11) from overvoltages, and the switching device (16) protects the device (11) from undervoltages. The fuses (15a-15k) and the switching device (16) are semiconductor components and may therefore be manufactured at the same time as the semiconductor device (11).
