MC33937APEK Three-phase FET pre-driver
33937A is a field-effect transistor (FET) front driver designed for three-phase motor control and similar uses. What is the use of SMARTMOS in integrated circuits (ICs)? Technology. The IC contains three high-side FET pre-drivers and three low-side FET pre-drivers.Three external bootstrap capacitors provide the gate charge of the high-side FETs. The MCU is connected to the device with 6 direct input control signals, an SPI port and an asynchronous reset IC interface to interrupt the signal. 5.0 and 3.0 V logic level inputs accept and 5.0 V logic level outputs
Features -------------------------------------------------- ------------------------------ fully compliant from 8.0 to 40 V, including 12 and 24 V, extended operating range from 6.0 to 58 V for automotive systems, covering 12 and 42 V systems >1.0 The ability to drive a gate to protect the CGD and CGS external FETs with the opposite charge injection from the protection includes charge pump support for the full FET driver at low battery voltage through the SPI port is programmable dead time while the output capability via secure SPI commands allows the product to be included in the Freescale product long-term supply plan, which guarantees supply for at least 15 years after launch
