DRV8880PWP

Overview

The DRV8880PWP is a dual H-bridge motor driver integrated circuit designed for low-voltage applications. It features two independent half-bridges capable of driving DC motors or stepper coils with peak currents up to 2.5 A per channel. The device operates from a supply voltage range of 2.7 V to 13.5 V and includes built-in protections such as overcurrent protection, thermal shutdown, and undervoltage lockout. It utilizes a PWM-compatible interface for speed and direction control.

Feature Summary

• Dual H-bridge architecture enabling independent control of two DC motors or one bipolar stepper motor
• Integrated high-side and low-side N-channel MOSFETs for efficient power switching
• Built-in diagnostic capabilities including fault indication and current sensing outputs
• Comprehensive protection mechanisms against overtemperature, overcurrent, and undervoltage conditions

Applications

• Home appliances requiring precise motor control
• Industrial automation systems with low-power actuators
• Office equipment such as printers and scanners
• Security systems involving motorized locks or blinds

Procurement Notes

Verify the exact suffix 'PWP' corresponds to the TSSOP-24 package and RoHS-compliant tape-and-reel or tube packaging options available from authorized distributors. Confirm that the ordering part number matches the specific temperature grade and packaging format required for your assembly process. Cross-reference with the manufacturer's latest datasheet to ensure no obsolete variants are selected.

Selection Notes

Select this component when dual independent motor control is needed within a compact footprint. Ensure the application voltage stays within the 2.7 V to 13.5 V range. Consider the thermal performance requirements given the 2.5 A peak current capability and the TSSOP-24 package's thermal resistance characteristics for your PCB layout design.

Part Context

This device belongs to Texas Instruments' DRV888x family of dual H-bridge drivers. It shares functional similarities with other members like the DRV8880PW but differs in package type and specific pinout configurations. The PWP suffix specifically denotes the plastic small-package outline with exposed pad variant, distinguishing it from other package options in the series.

Replacement Considerations

Direct replacements include other DRV8880 variants with compatible packages such as DRV8880PW if the original PWP package is unavailable. Verify pin-to-pin compatibility and electrical specifications before substitution. Alternative families may require schematic redesign due to differing control interfaces or protection features.
