The DRV10963PDSNR is a compact, two-channel motor driver IC. It provides efficient power delivery to 2 DC brushless motors with integrated, adjustible current regulation, over voltage protection and auto-shutdown. As the name suggests, the IC is especially designed for applications that require precise current control over a broad range of motor speeds. This IC is applicable in a range of industrial motor drives, such as servo motors and gearmotors, robotic controllers and drones, automotive applications and numerous other applications.

The DRV10963PDSNR offers a high-side MOSFET driver and a low-side MOSFET driver to provide a bidirectional input/output. The motoring current can be matched to the motor requirements, and the power stages can be short circuit and over temperature protected. Unloaded motors can be monitored through adjustable thresholds set in the circuit. The DRV10963PDSNR has a high PWM frequency, with a selectable PWM frequency of 6KHz to 800KHz.

The DRV10963PDSNR is configured for two particular operation modes and includes two integrated digital current-setting devices – one for each motor. The voltage regulation mode and current regulation mode are enabled by selecting the DRV10963PDSNR’s respective PWM pins. In the voltage regulation zone, the motor current is regulated for smooth constant speed operation even under full load or at low RPMs. In the current regulation zone, the motor current is controlled to protect the motor and prevent it from operating over temperature. This allows the motor to have a consistent rise time even when varying load conditions.

When the motor current passes a set threshold, the DRV10963PDSNR signals connected lamps or LEDs and trips to prevent the motor from further possible damage. The initialization and startup of the motor can be done in a ‘mode select’ pin. It also features 0 to 80% input voltage range, which makes it useful for both low voltage and high voltage applications. The DRV10963PDSNR is capable of operating at temperatures up to 150°C, making it suitable for fast-operating and performance-sensitive motors.

In summary, the DRV10963PDSNR is ideal for a wide range of industrial motor applications such as servo motors and gearmotors, robotic controllers and drones, automotive applications and numerous other applications due to its efficient power delivery and adjustable current regulation features.
