DRV8800PWP

Overview

The DRV8800PWP is a DMOS full-bridge motor driver manufactured by Texas Instruments, housed in a 28-pin HTSSOP package. It supports a supply voltage range of 5.5 V to 45 V and delivers an output current of up to 1.5 A per bridge. The device integrates overcurrent protection with adjustable thresholds via external resistors, thermal shutdown, and undervoltage lockout. Designed for brushed DC motors and solenoids, it operates within a junction temperature range of -40°C to +150°C.

Feature Summary

• Integrates two high-side and two low-side DMOS power switches configured as a full-bridge topology
• Provides adjustable overcurrent protection through external sense resistors connected to dedicated pins
• Includes built-in thermal shutdown circuitry to protect the device during excessive heat conditions
• Features undervoltage lockout to prevent operation when supply voltage is insufficient

Applications

• Brushed DC motor control in industrial automation systems
• Solenoid driving applications requiring bidirectional current flow
• Valve actuation mechanisms in process control equipment
• General-purpose motor drivers in consumer appliances

Procurement Notes

Verify the specific suffix 'PWP' confirms the 28-pin HTSSOP package variant. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Check for any recent product change notices affecting pinout or electrical characteristics. Ensure ordering quantities align with manufacturer standard packaging constraints.

Selection Notes

Select this component when a single-chip solution for bidirectional brushed DC motor control is required. The integrated full-bridge design eliminates the need for external discrete switching components. Consider the adjustable overcurrent threshold feature for protecting specific motor loads without fixed internal limits. Evaluate the thermal performance in your enclosure design due to the high junction temperature rating.

Part Context

The DRV8800 belongs to Texas Instruments' DRV880x family of DMOS full-bridge motor drivers. This series is designed to simplify motor control designs by integrating power stages and protection features into a compact package. The PWP suffix specifically denotes the 28-lead Power HTSSOP package, distinguishing it from other pin configurations in the same functional family.

Replacement Considerations

DRV8801PWP: Offers higher current capability (2.8 A) with similar interface and protection features. DRV8800PWPR: Identical electrical specifications but supplied in tape-and-reel packaging instead of tubes.
