Three phase field effect transistor
pre-driver
The 33GD3000 is a field effect transistor (FET) pre-driver designed for three
phase motor control and similar applications. It meets the stringent
requirements of automotive applications and is fully AEC-Q100 grade 1
qualified.
The IC contains three high-side FET pre-drivers and three low-side FET pre-
drivers. Three external bootstrap capacitors provide gate charge to the high-
side FETs.
The IC interfaces to a MCU via six direct input control signals, an SPI port for
device setup and asynchronous reset, enable and interrupt signals. Both 5.0 V
and 3.0 V logic level inputs are accepted and 5.0 V logic level outputs are
provided. The integrated circuit (IC) uses SMARTMOS technology.
