Rochester Electronics DRV8830DGQR Environmental and export classification status description

The DRV8830 is a dual H-Bridge motor driver IC manufactured by Texas Instruments. It is designed to control small DC motors and stepper motors in a wide range of applications. The device features a low on-resistance power stage that enables efficient operation. It is packaged in a small and compact QFN format, making it suitable for space-constrained designs. Functions - Bidirectional Motor Control: Capable of controlling the direction and speed of two DC motors. - PWM Control: Allows for pulse-width modulation (PWM) control for speed regulation. - Integrated Protection: Includes thermal shutdown, overcurrent protection, and undervoltage lockout. - Low power dissipation: Low on-state resistance minimizes power loss during operation. - Logic Level Control: Accepts standard logic levels for control inputs. Applications - Robotics: Used in robot servos and movement. - Consumer Electronics: Control for fans and actuators in devices. - Automated machinery: Control of small motors in automated systems. - Drones and UAVs: Motor control for propellers or flaps. - Home appliances: Used in motor control for washing machines, dryers, etc. Alternative Parts - DRV8833: Another dual motor driver from Texas Instruments but with different specifications and more extensive protection features. - L298N: An older dual H-Bridge driver that is widely used but less efficient compared to DRV8830. - TB6612FNG: A dual motor driver IC with PWM control and higher efficiency than L298N. - A4988: Stepper motor driver, suitable for applications requiring stepper control. Embedded Modules - Various development kits and motor driver modules integrate the DRV8830, such as TI's EVM (evaluation modules) that allow for prototyping and testing of systems with DRV8830.
