概述

Description

- The DRV8805PWPR is a Texas Instruments dual motor driver designed to drive two windings (bipolar stepper motors or two DC motors) with PWM current regulation.
- It provides two high-/low-side H-bridge outputs per channel, with current limit set by an external IREF resistor.
- Control is via simple STEP/DIR (and ENABLE) inputs, with built-in protections: overcurrent, overtemperature, undervoltage lockout, and fault reporting.
- Features include programmable decay/mode behavior and robust protection suitable for motors in printers, robotics, CNC, and similar applications.
- The PWPR suffix indicates the specific TI package/pinout (HTSSOP/TSSOP with an exposed pad) used for this part.
- In short: a compact, protected, current-regulated dual motor driver suitable for driving bipolar stepper motors or two DC motors with easily adjustable current.

Features

Here are the typical features of the DRV8805PWPR:
- Dual DMOS H-bridge outputs to drive a bipolar stepper motor.
- PWM-based current regulation with adjustable current limit (Imax) via a reference input.
- Robust protection: overcurrent protection (OCP), undervoltage lockout (UVLO), and overtemperature/thermal shutdown.
- Fault/status reporting: nFAULT (and related status signals as implemented).
- Simple control interface: STEP and DIR inputs; ENABLE to disable outputs; SLEEP and RESET for power-down/reset control.
- Wide operating voltage range suitable for common stepper systems.
- Compact PWPR package (TSSOP-like) with exposed pad for thermal dissipation.
- Suitable for smooth motor operation with current regulation to reduce heat and noise.

Package

HTSSOP-28 package with exposed pad (28-pin surface-mount, RoHS variant).

Pinout

- Pin count: 28 pins (PWPR package).
- Function: DRV8805PWPR is a dual full-bridge motor driver with PWM current regulation. It drives two DC motors or a two-coil stepper by two H-bridges (controlled via two input pairs: one for each bridge) and supports current regulation via an external sense resistor. It includes control pins (enable/sleep/reset) and status/diagnostic outputs (fault, etc.).

Manufacturer

- Manufacturer: Texas Instruments Incorporated (TI)
