MC33937

MC33937 Three phase field effect transistor pre-driver Rev. 14 — 18 November 2021 Product data sheet 1 General description The 33937A 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. 2 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 CGD 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 3 Applications Automotive systems: Cooling fan Water pump Actuator controls Fuel pump Electro-hydraulic and electric power steering Engine and transmission control Motor control Braking pump Belt starter generator Turbo pump NXP Se...
