    摘要: A single chip power diode includes a semiconductor body having an anode region coupled to a first load terminal and a cathode region coupled to a second load terminal. An edge termination region surrounding an active region is terminated by a chip edge. The semiconductor body thickness is defined by a distance between at least one first interface area formed between the first load terminal and the anode region and a second interface area formed between the second load terminal and the cathode region. At least one inactive subregion is included in the active region. Each inactive subregion: has a blocking area with a minimal lateral extension of at least 20% of a drift region thickness; configured to prevent crossing of the load current between the first load terminal and the semiconductor body through the blocking area; and at least partially not arranged adjacent to the edge termination region.

    摘要: A method of passively braking a motor to reduce a current motor speed includes generating at least one control signal to control a first load current generated by a first half bridge circuit and a second load current generated by a second half bridge circuit. During passive braking, the method includes synchronously driving a first high-side transistor and a second high-side transistor between their respective switching states at an alternating shorting frequency such that they are simultaneously in a same switching state, and synchronously driving a first low-side transistor and a second low-side transistor between their respective switching states at the alternating shorting frequency such that they are simultaneously in a same switching state, wherein the first high-side transistor and the second high-side transistor are driven in a complementary manner to the first low-side transistor and the second low-side transistor according to a predetermined duty cycle.

    摘要: An integrated circuit is presented. The integrated circuit includes a first terminal, a second terminal, a control terminal, a current monitor terminal, a power transistor coupled between the first terminal and the second terminal, and a replica transistor coupled between the first terminal and the current monitor terminal. The integrated circuit is configured to control a current between the first terminal and the second terminal based on a control signal applied to the control terminal. The integrated circuit is further configured to provide, at the current monitor terminal, a current monitor signal indicative of a value of the current.
