摘要： A voltage booster circuit including a pull-up capacitor connected to the supply line via a PMOS switching transistor. The other terminal of the pull-up capacitor is supplied with a pull-up voltage switching between a first value determining charging of the capacitor, and a second value higher than the first and determining pull-up of the capacitor. A negative voltage source presents an output connected to the control terminal of a switch transistor, and generates a negative voltage of a value lower than the first pull-up voltage value when charging the capacitor, so as to saturate the switch transistor and charge the capacitor to a voltage close to the supply voltage.

摘要： A method, and associated circuit, which can prevent the latch-down phenomenon in transistors which are protected from going out of their SOAs. By supplementing the first protection circuit (against moving out of the SOA) with a second protection circuit which can drive the control terminal of the transistor such that when, upon the voltage across the main conduction path of the transistor being increased, the value of the current flowing through said path would tend, due to the first protection, to drop below a predetermined lower limit, that value can be kept approximately constant and unaffected by the load as seen from the output terminal of the transistor; the transistor will at all events supply the load with some current up to the acceptable limit VMAX by the transistor.

摘要： The trimming circuit includes a plurality of trimmable resistances that may be coupled among them, each resistance being connected in parallel to a respective fuse. The trimming circuit allows burning any number of fuses according to a fixed trimming sequence using only one or two dedicated pins because it includes an input diode-connected transistor and a plurality of trimming transistors of different sectional area, each connected to force current throughout a respective one of the shunt fuses and coupled to the input diode-connected transistor such to mirror the current flowing therethrough. The fuses of the trimming circuit may be burnt by applying a trimming voltage to the diode-connected input transistor with a voltage generator connected between a dedicated pin of the circuit and a terminal at a reference potential, such to force a current therethrough as long as the mirrored currents flowing throughout the fuses burn them.

摘要： The device for protection against the short circuit of an MOS-type power device comprises at least one secondary branch cirucit arranged in parallel with a main branch circuit which includes the power transistor. The secondary branch includes a control MOS transistor having the same characteristics as the power transistor under control and the ability to conduct a current equal to a fraction of that flowing through the power transistor. The gate of the control transistor is connected directly with that of the power transistor. The secondary branch also includes means sensitive to temperature which, in the case of a current flow corresponding to the short circuit current of the power transistor, act on the gate common to the control and to the power transistors so as to lower its voltage and thus limit the conduction of same.
