Title:
OVERLOAD PROTECTION SYSTEM
Document Type and Number:
Japanese Patent JPH0946200
Kind Code:
A
Abstract:
To prevent destruction of a semiconductor switch such as a MOSFET without using a fuze or an IPS incorporating an overload protection circuit.
The overcurrent protection system 10 prevents an overload state of a drive means 16 supplying a current to a load 12 and is provided with an overcurrent detection means 30 to generate a supply current suppression instruction 30a when the overload state of the drive means 16 is detected and a supply current 21 to the drive means 16 is controlled and the current flowing to the drive means 16 is suppressed upon the receipt of the supply current instruction 30a to execute the control of preventing the overload state of the drive means 16 by a control means 20.
