MC33937APEKR2

NXP Semiconductors Document Number: MC33937 Rev. 10.0, 8/2018 Technical Data Three phase field effect transistor pre-driver 33937A The 33937A is a field effect transistor (FET) pre-drivers designed for three phase motor control and similar applications. It meets the stringent requirements of automotive applications and is fully AEC-Q100 grade 1 THREE PHASE PRE-DRIVER 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 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.
