Présentation

Description

The DRV8847PWPR is a dual H-bridge motor driver from Texas Instruments, designed for driving two DC motors, a single stepper motor, or other inductive loads. It supports a wide voltage range from 4.5V to 18V and can provide up to 1A continuous current per channel. The device features built-in protection mechanisms, including under-voltage lockout, over-current protection, over-temperature protection, and short-to-supply/ground protection, ensuring robust and reliable operation.
Key features include PWM control inputs for precise speed and torque management, current regulation to protect against excessive current draw, and configurable decay modes (slow, fast, and mixed) for optimal performance. The DRV8847 also offers a low-power sleep mode to minimize power consumption when the motor is not in use. Its small, thermally efficient package (TSSOP) is well-suited for compact designs. This motor driver is commonly used in applications like 3D printers, robotics, and industrial automation where multi-channel motor control is needed.
