L298 High-Power Dual H-Bridge Motor Driver – 7A 160W DC Motor Control Module

Description

Product Overview

The L298 High-Power Dual H-Bridge Motor Driver is an industrial-grade motor control module designed for high-current applications requiring robust performance and reliability. Unlike standard L298N modules limited to 2A, this high-power variant leverages the L298 logic architecture with enhanced power circuitry to deliver a continuous 7A per channel and a total output power of 160W .

This module serves as the ideal interface between your microcontroller (Arduino, PLC, STM32, Raspberry Pi) and high-power DC motors, linear actuators, or industrial automation equipment. It features optocoupler isolation between the control logic and high-power stages, protecting your sensitive microcontroller from electrical noise, voltage spikes, and ground loops commonly found in industrial environments .

Whether you are building heavy-duty robotic platforms, automated conveyor systems, electric vehicle prototypes, or industrial machinery, this driver provides the power handling and noise immunity required for reliable operation.

Key Features

• High-Current Dual H-Bridge: Drives two DC motors simultaneously with a rated continuous output current of 7A per channel and peak current capacity of 50A (transient), enabling control of high-torque motors and actuators .

• 160W Total Output Power: Capable of delivering substantial power to your motors, with support for 12V motors up to 40W and 24V motors up to 115W continuously .

• Optocoupler Isolation: Features signal optocoupler isolation between the logic inputs and the power stage. This critical feature provides:

  • Protection for microcontrollers from back-EMF and voltage spikes

  • Elimination of ground loop interference

  • Enhanced noise immunity in industrial environments

• Wide Operating Voltage Range: Accepts motor supply voltages from 6.5V to 27V, making it compatible with 12V, 18V, and 24V industrial motor systems .

• Comprehensive Protection Circuitry:

  • Undervoltage Protection: Prevents module damage during brownout conditions by disabling outputs when voltage drops too low

  • TVS Protection: High-power transient voltage suppression diodes absorb voltage spikes and enhance EMC performance

  • Electrostatic Discharge (ESD) Circuit: Protects against static damage during handling and operation

• PWM Speed Control: Enable signal terminals (ENA/ENB) accept PWM signals for precise speed regulation, with a supported frequency range of 0-10kHz and minimum pulse width of 10μs .

• Wide Logic Compatibility: Control signal voltage range of 3V-6.5V ensures compatibility with both 5V microcontrollers (Arduino) and 3.3V systems (ESP32, Raspberry Pi Pico) .

• Industrial Temperature Range: Rated for operation from -25°C to +80°C, suitable for demanding environments and outdoor applications .
