TI’s MC831x family of Fully Integrated motor drivers brings in both motor control and MOSFETs to offer a one-chip solution for motor drivers. Integrated control allows for code-free trapezoidal and field-oriented control settings with only an external MCU needed for configuring settings over I. These devices range from 4.5-V to 40-V and up to 8-A peak current and supports motor drives up to <70W.

TI’s MCx family of control and gate drivers integrates control functionality into the driver for a device that can spin the motor without MCU assistance. Integrated control and MOSFETs allows for complete system-on-chip solution for code-free trapezoidal and field-oriented control via programmable EEPROM and configuring settings over an I²C or hardware interface. Fully integrated MCx831x devices provide the smallest BOM size for systems that traditionally use an external MCU and N-type power MOSFETs for traditional motor control. Current sensing is integrated into the device without the need for external sense resistors. The MCx831x devices include an integrated charge pump for high-side MOSFET enhancement as well as an adjustable buck regulator and LDO to support external logic-level power rails.
