DRV8412DDW

Full Half-Bridge (H Bridge) Drivers Overview

The DRV8412DDW is a dual full-bridge PWM motor driver manufactured by Texas Instruments, designed for driving DC and stepper motors. It features four half-bridge outputs with a continuous output current of 3A per channel and a peak current of 6A. The device operates within a supply voltage range of 10.8V to 13.2V and supports load voltages from 0V to 52.5V. Key electrical parameters include an on-resistance of 110 milliohms for both low-side and high-side switches. It utilizes a 44-HTSSOP package and functions across a junction temperature range of -40°C to 150°C.

• Includes comprehensive protection mechanisms such as overcurrent protection, overtemperature shutdown, short-circuit protection, and undervoltage lockout.
• Supports PWM interface for precise motor speed and direction control.
• Features status flag output for monitoring operational states.

Full Half-Bridge (H Bridge) Drivers Applications

• DC motor control systems
• Bipolar stepper motor drivers
• Thermoelectric cooler (TEC) controllers

Full Half-Bridge (H Bridge) Drivers Procurement Notes

Verify the specific suffix 'DDW' against the manufacturer's latest datasheet to confirm pinout and package dimensions. Ensure compatibility with the required thermal management solution, as the device generates significant heat at high currents. Confirm RoHS compliance status if environmental regulations apply to your assembly process. Cross-reference the ordering number with official distributors to avoid counterfeit components.

Full Half-Bridge (H Bridge) Drivers Selection Notes

Select this component when a dual H-bridge configuration is required for driving two separate DC loads or a single stepper motor. It is suitable for applications needing moderate current levels up to 3A per channel without external MOSFETs. Consider the 44-pin HTSSOP package constraints for PCB layout. Evaluate thermal performance requirements early, as the integrated power stage may require heatsinking under heavy load conditions.

Full Half-Bridge (H Bridge) Drivers Part Context

The DRV8412 belongs to the DRV84x2 family of dual full-bridge PWM motor drivers from Texas Instruments. This series is engineered for robust motor control applications, offering integrated power stages to simplify design. The DDW variant specifically denotes the 44-pin PowerTSSOP package. It shares functional similarities with other members like the DRV8432 but differs in pin count and current capabilities.

Full Half-Bridge (H Bridge) Drivers Replacement Considerations

The DRV8412DDWR is a reel-packaged equivalent of the same core device. For legacy designs, the DRV8432DKDR was previously available but is now obsolete; however, it uses a different 36-pin package and higher current ratings, requiring schematic and layout modifications.
