VNH5050A-E

VNH5050A-E Description

The VNH5050A-E from STMicroelectronics is a high-performance half-bridge motor driver designed for brushed DC motor applications. Part of the VIPower™ series with ECOPACK® packaging, it integrates Power MOSFET technology to deliver 30A continuous output current with a 5.5V to 18V operating range. This automotive-grade IC is ideal for demanding environments, offering robust performance in surface-mount (PowerSSO-36) configurations. Though now obsolete, its legacy design remains relevant for systems requiring high-efficiency motor control with parallel or PWM interfaces.

VNH5050A-E Features

• High Current Handling: Supports 30A output with low RDS(on) for minimal power dissipation.
• Wide Voltage Range: Operates from 5.5V to 18V, compatible with 12V automotive systems.
• Integrated Protection: Built-in thermal shutdown, overcurrent, and short-circuit safeguards.
• Flexible Control: Parallel and PWM interfaces for precise motor speed/direction control.
• Automotive Compliance: ROHS3 and REACH compliant, meets stringent automotive reliability standards (MSL 3).
• Compact Design: PowerSSO-36 package optimizes space in PCB layouts.

VNH5050A-E Applications

• Automotive Systems: Power window lifters, seat adjusters, and sunroof controls.
• Industrial Automation: Conveyor belts, actuator drives, and robotic arms.
• Consumer Electronics: High-torque DC motor applications in appliances or power tools.
• Battery-Powered Devices: Efficient motor control in portable equipment.

Conclusion of VNH5050A-E

The VNH5050A-E excels in high-current DC motor driving, combining efficiency, protection features, and automotive-grade durability. While obsolete, its design principles remain valuable for legacy systems or replacements requiring robust half-bridge control. Engineers seeking alternatives should consider STMicroelectronics' newer VIPower™ offerings with enhanced features.
