Monolithically integrated control circuit for use in power electronics system, has bottom- level shifter for transmission of signal from control logic to bottom drive unit and designed as arrangement of up and down level shifter branches

摘要

The circuit (10) has a bottom- level shifter (70) for transmission of an input signal from a control logic (20) to a bottom drive unit (50). The shifter is designed as an arrangement of up and down level shifter branches (72, 74). A signal evaluation circuit (76) is provided downstream to the level circuit. Outputs of the branches are connected to inputs of the signal evaluation circuit. An output of the evaluation unit provides an input signal to the unit. The branch (72) is formed from two partial branches, which are formed from an arrangement of N-channel transistors. An independent claim is also included for a method for transmission of an input signal from a control logic to a bottom drive unit.
