VNH2SP30 30A Single Monster Motor Driver Module

VNH2SP30 30A Single Monster Motor Driver Module is a robust, high-current H-bridge motor driver built around the powerful STMicroelectronics VNH2SP30 IC, designed specifically for driving large DC motors and heavy loads. This module provides a safe, efficient interface between low-voltage microcontrollers and high-current mechanical systems. Consequently, it handles continuous currents up to 30 A and can manage peak currents up to 60 A, making it an excellent choice for demanding robotics and automotive applications. Furthermore, the VNH2SP30 integrates protection features like thermal shutdown and undervoltage lockout, which significantly enhance the system’s durability and reliability. Utilize this single-channel monster driver to achieve precise speed and direction control over your most power-hungry motors.

Key Features:

• High Current Capability: The module drives continuous loads up to 30 A, and simultaneously handles instantaneous peak currents of up to 60 A, supporting large brushed DC motors.
• PWM Speed Control: It offers full Pulse Width Modulation (PWM) control for precise motor speed management, functioning effectively at frequencies up to 20 kHz.
• Integrated Protection: Built-in safeguards include thermal shutdown protection, current limiting, and undervoltage lockout, ensuring robust and long-term operation.
• Diagnostic Feedback: A dedicated current sense pin provides an analog voltage proportional to the load current, allowing the microcontroller to monitor motor usage and detect stalls.
• Low R_DS(on): The low MOSFET On-Resistance (typically 19 mΩ total) minimizes power dissipation and improves overall efficiency.
