DRV8872DDA

Overview

The DRV8872DDA is a single H-bridge motor driver manufactured by Texas Instruments, designed for brushed DC motor applications. It operates within a supply voltage range of 6.5 V to 45 V and delivers an output current of 3.6 A. The device utilizes NMOS technology and features PWM control interfaces. It is housed in an 8-SO-PowerPad surface-mount package with a thermal pad for efficient heat dissipation. The component supports a wide operating temperature range from -40°C to +125°C and includes integrated protections against under-voltage, over-current, and overheating conditions.

Feature Summary

• Integrates a full H-bridge driver with four N-channel MOSFETs for bidirectional motor control
• Features integrated current regulation based on analog input and external sense resistor voltage
• Supports PWM speed control with selectable current decay modes
• Includes comprehensive protection mechanisms for fault and short-circuit scenarios

Applications

• Brushed DC motor control systems
• Stepper motor winding drivers
• General-purpose load switching applications

Procurement Notes

Verify the specific ordering suffix and package variant when sourcing, as availability may vary between tube and reel configurations. Confirm that the component meets required environmental standards such as RoHS compliance. Check for end-of-life status or obsolescence notices from the manufacturer before finalizing procurement plans to ensure long-term supply stability.

Selection Notes

Select this component for applications requiring a single H-bridge configuration with high peak current capability. Ensure the system design accommodates the 6.5 V to 45 V supply voltage range and provides adequate thermal management for the SO-PowerPad-8 package. Verify compatibility with PWM control signals and check if the integrated current regulation meets the specific torque and speed requirements of the target motor load.

Part Context

The DRV8872DDA belongs to the DRV887x family of motor drivers from Texas Instruments. This series is engineered for robust performance in automotive and industrial environments. The part shares functional similarities with other variants in the lineup but differs in packaging and specific qualification levels. It serves as a core power stage solution for motion control designs requiring reliable H-bridge operation.

Replacement Considerations

The DRV8870DDAR is documented as a parameter-equivalent alternative. Verify pinout compatibility and electrical specifications before substitution.
