Übersicht

Description

The DRV8424PWPR is TI’s dual full‑bridge motor driver. It provides two high‑current H‑bridges that can drive two motor windings (DC motors or stepper windings) from a single device. Key features include integrated MOSFETs, current regulation via an external sense resistor and reference voltage (programmable peak current), and protection such as overcurrent, undervoltage, overtemperature, and fault reporting. Control is via simple logic inputs (per-bridge IN/EN or PWM control), allowing easy integration with basic microcontroller timing. The PWPR package denotes TI’s RoHS-compliant variant of the device.
Typical uses are in printers, robotics, 3D printers, CNC machines, and other applications requiring compact dual-motor drive with protection and current control. For design details—pinout, current-setting formulas, decay modes, and thermal considerations—consult the DRV8424PWPR datasheet.

Features

Here are the key features of the DRV8424PWPR:
- Dual high-current stepper motor driver (two output channels) with current-regulated operation
- Adjustable current limit per winding via external sense resistor
- Microstepping support (up to 1/8-step)
- PWM current regulation with decay modes for smoother torque
- Wide supply voltage range (suitable for typical 12–42 V applications)
- Protective features: undervoltage lockout, overcurrent protection, thermal shutdown (with thermal warning)
- Fault and status reporting: FAULT and FLAG pins
- Simple control interface: STEP and DIR inputs; ENABLE; SLEEP/RESET (or equivalent control pins)
- Fast, clean shutoff and protection against abnormal conditions
- Integrated protection for stable, safe operation in demanding motor applications
- Packaging: PWPR variant (Texas Instruments small-outline package, RoHS-compliant)
Common applications: 2-phase stepper motors for CNC, 3D printers, robotics, and other precision motor drives.

Package

The DRV8424PWPR comes in a 28‑pin HTSSOP (Power‑SSOP) package.

Pinout

- Pin count: 28 pins (PWPR package, HTSSOP-28)
- Function: Dual full-bridge motor driver for stepper/DC motors. Provides two H-bridges to drive two windings with constant-current control and protection. Each bridge is controlled by a pair of logic inputs (e.g., IN1/IN2 for channel A, IN3/IN4 for channel B) plus enable/diagnostic pins. Includes power, ground, sense/current regulation circuitry, and related protection features.

Manufacturer

Manufacturer: Texas Instruments (TI).
What kind of company: An American multinational semiconductor company that designs and manufactures integrated circuits and embedded processing solutions, specializing in analog, mixed-signal, and embedded processing products.
