DRV8813PWP

Overview

The DRV8813PWP is a bipolar stepper motor driver from Texas Instruments, housed in a 28-pin HTSSOP package. It supports a supply voltage range of 8.2 V to 45 V and delivers an output current of 1.75 A. The device operates within a temperature range of -40°C to +85°C. Key features include integrated charge pump circuitry for high-side gate drive, programmable current control via an analog reference or PWM input, and multiple microstepping resolutions. Protection mechanisms encompass overcurrent protection, thermal shutdown, and under-voltage lockout.

Feature Summary

• Integrates a charge pump to enable reliable high-side N-channel MOSFET driving without external bootstrap components.
• Supports flexible microstepping with selectable resolutions including full, half, quarter, eighth, sixteenth, thirty-second, sixty-fourth, and one-twelfth-eighty-fourth steps.
• Features adjustable current limiting through an analog voltage reference or a PWM signal for precise torque control.

Applications

• Office automation equipment such as printers and scanners
• Security systems including CCTV camera pan-tilt mechanisms
• Automotive interior applications like seat adjustment actuators

Procurement Notes

Verify the specific suffix 'PWP' indicates the tube packaging variant rather than the 'PWPR' reel variant. Confirm RoHS compliance status and humidity sensitivity level prior to assembly planning. Ensure the ordering part number matches the required package style and tape/reel specifications for your manufacturing line.

Selection Notes

Select this component when designing bipolar stepper motor drives requiring up to 1.75 A continuous current. It is suitable for applications needing integrated protection features and multiple microstepping options. Consider the HTSSOP-28 package constraints and thermal dissipation requirements relative to the expected load current and ambient operating conditions.

Part Context

This device belongs to the DRV88xx family of integrated stepper motor drivers from Texas Instruments. These drivers are designed to simplify motion control designs by integrating power switches, drivers, and protection circuits into a single compact package, reducing board space and design complexity compared to discrete solutions.

Replacement Considerations

The DRV8813PWPR is the reel-packaged equivalent of the DRV8813PWP. Verify pin compatibility and electrical specifications if substituting with other DRV88xx series devices, noting that output current ratings and package types may vary across the family.
