Definitions
- the present invention relates to the field of electronics.
- the present invention has particularly advantageous applications in the field of automotive electronics, and in particular in the field of "H-bridge" type devices and power drivers.
- Figure 2 illustrates a system according to the state of the art. It can be observed in FIG. 2 that, in the event of detection of a current with a too high intensity called "overcurrent", all the transistors are cut at the same time.
- the inductive discharge phase in the freewheeling diodes causes a substrate injection into the electronic circuits and forces expensive semiconductor processes to resist.
- the inductive discharge phase in the freewheeling diodes also generates a rise in the supply voltage on the highside side (that is to say on the side connected to the supply voltage). This makes it necessary to increase the decoupling capacities and therefore the cost.
- the present invention intends to overcome the disadvantages of the prior art by proposing a method for eliminating or in any case to greatly reduce the freewheeling diode injection in the case of a current detection having an intensity too high said "overcurrent” or detection of phenomena of the type "thermal shutdown” in English, that is to say, a cut for a reason of excessive temperature.
- the present invention relates, in its most general sense, to a method for limiting the current in an "H-bridge" type device comprising a plurality of transistors, remarkable in that it comprises the following steps:
- the method according to the present invention makes it possible to eliminate or greatly reduce the free-wheel diode injection in the case of a current detection with a too high intensity called “over current” or a thermal phenomenon called “overcurrent”. thermal shutdown ".
- the method according to the present invention allows the implementation of semiconductor process with low immunity to substrate injection.
- the method according to the present invention also makes it possible to reduce the so-called overshoot phenomena of the supply voltage and thus to reduce the decoupling capacitors.
- the method according to the present invention also makes it possible to reduce the size of the freewheeling diodes.
- said failure is linked to a current with a too high intensity called "overcurrent”.
- said failure is linked to a thermal phenomenon.
- said detection on the transistors opposite to said transistor of the discharge of the energy accumulated at the output is carried out by a current detector on the opposite transistors.
- said detection on the transistors opposite to said transistor of the discharge of the energy accumulated at the output is carried out by a voltage detector on the opposite transistors.
- the present invention also relates to a system for limiting the current in an "H-bridge" device comprising a plurality of transistors, remarkable in that it comprises means for:
- FIG. 2 illustrates a system according to the state of the art
- FIG. 3 illustrates the system implementing the method according to the present invention, in one embodiment.
- Figure 1 illustrates the method according to the present invention in one embodiment.
- the present invention relates to a method for limiting the current in an "H-bridge" device comprising a plurality of transistors T1, T2, T3, T4, comprising the following steps:
- the failure is related to a current with a too high intensity called "overcurrent”.
- the failure is related to a thermal phenomenon.
- the detection on the transistors opposite said transistor T of the discharge of the energy accumulated at the output is carried out by a current detector on the opposite transistors.
- the detection on the transistors opposite to said transistor T of the discharge of the energy accumulated at the output is carried out by a voltage detector on the opposite transistors.
- the present invention also relates to a system for limiting the current in an "H-bridge" type device comprising a plurality of transistors T1, T2, T3, T4.
- This system comprises means for:
- Figure 3 illustrates the system implementing the method according to the present invention, in one embodiment.
- current detection with a too high intensity called "overcurrent”
- not all the transistors are cut at the same time. This is expected to detect on the transistors opposite to the first transistor the discharge of the accumulated energy output.
- the method according to the present invention makes it possible to eliminate or greatly reduce the freewheeling diode injection in the case of a current detection having a too high intensity called "over current” or a thermal phenomenon evoked more high.
- the method according to the present invention allows the implementation of semiconductor process with low immunity to substrate injection.
- the method according to the present invention also makes it possible to reduce the so-called "overshoot" phenomenon in the English language of the supply voltage and thus to reduce the decoupling capacitors.
- the present invention applies to all types of circuits having "high sides” or circuits having multiple MOS with freewheel diode phases.
