Abstract
A method for limiting the current in a device of “H-bridge” type having a plurality of transistors including the following steps: detection of a failure in a transistor from among the plurality of transistors; disabling of the transistor in which a failure has been detected; detection in the transistors opposite to the transistor, of the discharging of the energy accumulated at output; and disabling of the other transistors of the plurality of transistors. A system for limiting the current in a device of “H-bridge” type having a plurality of transistors is also disclosed.

A method for limiting the current in an ‘H-bridge’ device including a plurality of transistors (T1, T2, T3, T4), the method comprising:
- detecting a failure on one transistor from among said plurality of transistors;
- turning off said transistor on which a failure has been detected;
- detecting, on the transistors opposite said transistor, the discharge of the accumulated output power;
- and
- turning off the other transistors of said plurality of transistors.
