Title:
駆動出力側を備えた電子素子の保護回路
Document Type and Number:
Japanese Patent JP3559524
Kind Code:
B2
Abstract:
The invention relates to a protective circuit for electronic modules, especially driver modules, for protecting against polarity reversal and against rupturing of the neutral conductor. A first protective diode (D1) is arranged, with the cathode thereof, in the supply lead (3) such that it leads to the t supply potential (GND). Said supply lead is supplied by the lower-lying supply potential (GND) and is provided for the circuit parts (A1) connected in incoming circuit from the module (B1). A second protective diode (D2) is arranged, with the diode thereof, in the supply terminal (4) of the module (B1) such that it leads to the supply potential (GND), said supply terminal being supplied by the lower-lying supply potential (GND).
