概要

Description

The DRV8256PPWPR is a Texas Instruments dual full-bridge motor driver with integrated MOSFETs, intended for bidirectional control of two DC motors or a stepper motor.
Key points:
- Two independently controllable bridges with logic inputs, suitable for PWM speed control.
- Built-in protections: undervoltage lockout, overcurrent protection, overtemperature shutdown, and fault/status reporting.
- Shoot-through protection and configurable decay/braking options.
- Interface: VM (motor supply), GND, input pins per channel, enable, and FAULT/STATUS outputs to a microcontroller.
- Packaging: PWPR variant (package type/specifications in the TI datasheet; check for pinout and thermal guidance).
Common uses:
- Small robotics, printers, conveyors, and other applications needing two motor channels with protected, easy MCU control.
Note: The datasheet provides exact electrical specs (current capability, voltage range, timing, and pinout). This overview covers purpose and typical usage, not detailed constants.

Features

Here are the key features of the DRV8256PPWPR:
- Dual DMOS H-bridge motor drivers with PWM current regulation for two windings
- External sense resistor and VREF settable coil current; independent regulation per channel
- Step and Direction control inputs with ENABLE; MS1/MS2 for microstepping resolution
- PWM current regulation with selectable decay modes for smooth operation
- Fault and diagnostic outputs for status monitoring
- Protection: overcurrent, undervoltage, overtemperature, and short-circuit to GND/VCC with latch options
- Wide supply voltage range suitable for various stepper and brushed DC motors
- Low standby/idle current and compact QFN packaging (PPWPR)
Note: Always consult the latest TI datasheet for exact electrical limits, pinout, and programming details.

Package

HTSSOP-28 (Power-SSOP) package; RoHS-compliant with exposed-pad variant indicated by the PWPR suffix.

Pinout

- Pin count: 20 pins (PWPR package, HTSSOP-20 style).
- Function: TI DRV8256 is a dual full-bridge motor driver designed to drive a two‑phase stepper motor (or two DC motors) with PWM/current regulation. It provides two DMOS bridges, input control pins, enable/sleep, fault/diagnostic outputs, and protection features (overcurrent, undervoltage, thermal).

Manufacturer

- Manufacturer: Texas Instruments (TI).
- About the company: TI is an American multinational semiconductor company that designs and manufactures analog and embedded processing ICs, serving automotive, industrial, consumer electronics, and other markets.
