Overview
The NXP® MC33883HEG is an H-bridge gate driver IC, also known as a full-bridge pre-driver, designed with integrated charge pump and independent high and low side gate driver channels. This device is powered by SMARTMOS technology and is AEC-Q100 qualified, making it suitable for various automotive and industrial applications. The MC33883HEG allows for the independent control of four separate input pins, enabling it to be configured as two independent high side gate drivers and two independent low side gate drivers. It supports high pulse-width modulation (PWM) frequencies and can drive large gate-charge MOSFETs efficiently.
