DRV8842MPWPREP

Overview

The DRV8842MPWPREP is a single H-bridge current-controlled motor driver manufactured by Texas Instruments. It provides an integrated solution for driving DC motors, stepper motor coils, or other actuators. The device features N-channel power MOSFETs configured as an H-bridge with separate inputs to independently control each half. It supports an operating supply voltage range of 8.2 V to 45 V and can deliver up to 5 A peak or 3.5 A RMS output current at 24 V and 25°C with proper heatsinking. The component is housed in a thermally enhanced 28-pin HTSSOP package with PowerPAD.

Feature Summary

• Integrates a single H-bridge driver with independent control inputs for each half-bridge leg.
• Includes built-in protection functions such as overcurrent protection, short-circuit protection, undervoltage lockout, and overtemperature shutdown.
• Features a five-bit winding current control mechanism allowing up to 32 distinct current levels.
• Provides a low MOSFET on-resistance design to minimize conduction losses.

Applications

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

Procurement Notes

Verify the specific suffix MPWPREP against the manufacturer's official datasheet to confirm it denotes the standard production variant within the DRV8842 family. Ensure compatibility with the required 28-pin HTSSOP footprint and thermal management requirements for the intended current load. Confirm that the ordering information matches the latest package option addendum provided by Texas Instruments.

Selection Notes

Select this component when a single high-current H-bridge is required for brushed DC or bipolar stepper motor applications. It is suitable for designs needing independent half-bridge control and integrated fault protection. Consider the thermal performance of the HTSSOP package relative to the expected RMS current and ambient temperature conditions.
