Abstract

The motor driving inverter circuit module includes first-phase, second-phase, and third-phase high voltage drivers generating first-phase, second-phase, and third-phase upper arm and lower arm driving signals in response to input signals for driving the first-phase, second-phase, and third-phase upper and lower arms and a first-phase, second-phase, and third-phase upper arm and lower arm transistors, generating first-phase, second-phase, and third-phase motor driving output signals in response to the first-phase, second-phase, and third-phase upper arm and lower arm driving signals of the first-phase, second-phase, and third-phase high voltage drivers. The first-phase, second-phase, and third-phase high voltage drivers and the first-phase, second-phase, and third-phase upper arm and lower arm transistors are respectively integrated into separate chips.
