NXP USA Inc. MC33937APEK

Description
The MC33937A is a field effect transistor (FET) predriver 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 predrivers and three low-side FET predrivers. 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.

Features and Benefits:
Extended operating range from 6.0 V to 58 V covers 12 V and 42 V systems
Gate drive capability of 1.0 A to 2.5 A
Fully specified from 8.0 V to 40 V, covers 12 and 24 V automotive systems
Device protection against reverse charge-injection from CoD and CGs of external FETs
Dead time is programmable via the SPI port
Simultaneous output capability enabled via safe SPI command
AEC-Q100 grade 1 qualified
