The DRV10987SPWPR is designed and produced by Texas Instruments as part of their family of motor drivers, controllers and power management ICs. The device is a single-chip solution for controlling 2-phase brushless motors, particularly in applications where Hall effect sensors are used for feedback. It combines a motor driver and controller, a gate driver and a complete power stage (high side, low side and out drivers) in one IC, providing a complete and highly integrated solution for BLDC control applications.

The DRV10987SPWPR has an integrated three-channel half-bridge motor driver, enabling it to drive both 2-phase and 4-phase BLDC motors. The motor driver features low saturation voltage and true linear current-sense BEMF-detection, providing excellent protection and improved motor accuracy. The full-bridge gate driver with power diodes makes it possible to drive the high side and low side FETs without the need for external bootstrap components, further reducing the number of passive components typically required in BLDC designs.

The device also contains a powerful integrated control MCU that is used to control the current loop, voltage loop and other motor control parameters. It has integrated logic to detect and respond to Hall effect sensors, and also supports various sensorless algorithms such as Back EMF, Zero Crossing and Lock-In. The integrated MCU can be programmed via SPI (Serial Peripheral Interface), enabling the user to customize the behaviour and interface of the device for their specific application.

The DRV10987SPWPR is ideally suited for a wide range of medium to high voltage applications, such as automotive, industrial and medical. It is especially well suited for applications that require high efficiency, such as electric vehicles and drones. Thanks to its high efficiency, the device can help reduce system power consumption by minimizing power losses in the power stage and motor control loops.

In conclusion, the DRV10987SPWPR is an excellent single-chip solution for controlling brushless DC motors in a wide variety of applications. It combines a powerful motor driver and controller with a gate driver and a complete power stage in one package, providing a highly integrated and efficient solution for BLDC control.
