DRV8842PWP

Overview

The DRV8842PWP is a single H-bridge current-controlled motor driver from Texas Instruments, housed in a thermally enhanced 28-pin HTSSOP PowerPAD package. It supports an operating supply voltage range of 8.2 V to 45 V and delivers up to 5 A peak or 3.5 A RMS output current at 24 V and 25°C with proper heatsinking. The device features five-bit winding current control for up to 32 current levels and includes a built-in 3.3-V reference output. Internal shutdown functions provide overcurrent protection, short-circuit protection, undervoltage lockout, and overtemperature protection.

Feature Summary

• Integrates N-channel power MOSFETs configured as an H-bridge for driving DC motors or stepper coils
• Provides independent inputs to control each half of the H-bridge
• Includes comprehensive internal shutdown functions for system protection

Applications

• Printers
• Scanners
• Office automation machines
• Gaming machines
• Robotics

Procurement Notes

Verify the specific suffix against the manufacturer's official documentation to confirm temperature rating and packaging details. The PWP suffix denotes the HTSSOP-28 package with a PowerPAD thermal pad. Ensure compatibility with the target application's thermal management requirements, as the rated continuous current depends on adequate heat dissipation. Confirm RoHS compliance status through the latest datasheet revision.

Selection Notes

Select this component when a single high-current H-bridge is required for brushed DC or bipolar stepper motor applications. The integrated current control simplifies design by reducing external components. Consider the thermal performance of the PowerPAD package relative to the expected load current and ambient temperature. Verify that the 8.2 V minimum supply voltage aligns with the system's power architecture.

Part Context

The DRV8842 belongs to the DRV88xx family of motor drivers designed for automated equipment. It serves as a complete solution by integrating both control logic and power stages. The device is intended for applications requiring precise current regulation and robust protection features within a compact surface-mount footprint.

Replacement Considerations

DRV8842PWPR: Same functional specifications but supplied in reel packaging instead of tubes.
