DRV8262DDWR

Overview

The DRV8262DDWR is a wide-voltage, high-power H-bridge motor driver manufactured by Texas Instruments. It integrates two H-bridges to drive one or two brushed DC motors or one bipolar stepper motor. The device supports a supply voltage range of 4.5 V to 60 V and features integrated current detection with regulation for the high-side MOSFETs. It offers peak output currents up to 16 A in dual H-bridge mode and 32 A in single H-bridge mode at 24 V and 25°C using the DDW package. Key specifications include low RDS(ON) values of 100 mΩ (dual) and 50 mΩ (single), programmable PWM chopping times, and a low-current sleep mode drawing 3 µA.

Feature Summary

• Integrates two H-bridges capable of driving one or two brushed DC motors or one bipolar stepper motor
• Features integrated high-side MOSFET current detection and regulation to eliminate external shunt resistors
• Supports multiple programmable interfaces including Phase/Enable and IN/IN configurations
• Includes comprehensive protection mechanisms such as UVLO, OCP, and thermal shutdown

Applications

• Driving single or dual brushed DC motors in industrial automation
• Controlling bipolar stepper motors in motion control systems
• Powering thermoelectric coolers (TECs)
• Industrial equipment requiring high-current motor actuation

Procurement Notes

Verify the specific package variant, as performance metrics like peak current depend on the package type (e.g., DDW vs. DDV). Confirm that the application voltage does not exceed the 60 V maximum rating. Ensure thermal management solutions are adequate for the expected load conditions given the high current capabilities. Check for compatibility with the required logic input voltage levels (1.8 V, 3.3 V, or 5.0 V).

Selection Notes

Select this component when a single IC solution is needed to drive multiple motors or high-current loads without external power switches. It is suitable for applications requiring integrated current sensing to save board space and reduce system cost. Consider the DDW package if the required peak current aligns with its 16 A (dual) or 32 A (single) ratings. Evaluate the need for programmable PWM chopping to optimize motor performance and noise.

Part Context

The DRV8262 belongs to Texas Instruments' family of H-bridge motor drivers designed for industrial applications. It complements other drivers like the DRV8462 and DRV8962 but distinguishes itself with integrated current regulation and support for both DC and stepper motors. The device is part of the broader PMIC portfolio aimed at simplifying motor control designs through high integration and robust protection features.

Replacement Considerations

Direct substitutes within the same family include the DRV8262DDV, which offers higher peak current ratings due to its different package. For applications requiring only half-bridge configurations, the DRV8962 series may be considered, though it lacks the full H-bridge integration. Verify pinout and thermal characteristics before swapping packages.

FAQ

What is the difference between the DRV8262DDW and DRV8262DDV packages?

The primary difference lies in their peak current capabilities. The DDW package supports up to 16 A peak in dual H-bridge mode and 32 A in single H-bridge mode, while the DDV package supports higher currents due to improved thermal performance.

Does the DRV8262 require external shunt resistors for current sensing?

No, the DRV8262 integrates high-side MOSFET current detection and regulation, eliminating the need for external shunt resistors. This reduces board area and system cost.

Can the DRV8262 drive a bipolar stepper motor?

Yes, the device integrates two H-bridges that can be configured to drive a single bipolar stepper motor, in addition to supporting one or two brushed DC motors.
