Power Distribution Switches, Load Drivers

VB325SP Description

The VB325SP from STMicroelectronics is a bipolar power driver designed for low-side switching applications, offering robust performance in power management systems. Part of the VIPower™ series, this obsolete but reliable component delivers a maximum output current of 10A with a 1:1 input-to-output ratio, making it ideal for precision control in demanding environments. Its 4.5V to 5.5V supply voltage range ensures compatibility with standard logic levels, while the 30V maximum load voltage accommodates a variety of industrial and automotive applications. Packaged in a surface-mount PWRSO10 tube, the VB325SP is engineered for efficiency and durability, featuring over-temperature fault protection and a status flag for real-time monitoring.

VB325SP Features

• Bipolar Output Type: Ensures high current drive capability for low-side configurations.
• Status Flag: Provides diagnostic feedback for system health monitoring.
• Over-Temperature Protection: Safeguards against thermal damage, enhancing reliability.
• ROHS3 Compliant & REACH Unaffected: Meets stringent environmental and safety standards.
• Wide Operating Voltage (4.5V–5.5V): Compatible with 5V logic systems.
• 10A Output Current: Supports high-power loads with minimal dropout.
• Parallel Interface: Simplifies integration into existing control architectures.

VB325SP Applications

The VB325SP excels in industrial automation, motor control systems, and automotive electronics, where precise power switching is critical. Its low-side configuration makes it suitable for driving solenoids, relays, and lamps, while the status flag aids in fault detection for predictive maintenance. In power distribution networks, the device’s high current handling and thermal protection ensure uninterrupted operation under heavy loads. Additionally, its surface-mount design is optimal for space-constrained PCB layouts in consumer electronics and embedded systems.

Conclusion of VB325SP

Though marked obsolete, the VB325SP remains a high-performance power driver for legacy systems requiring bipolar switching and robust fault protection. Its VIPower™ technology, combined with 10A output capability and diagnostic features, positions it as a dependable choice for industrial and automotive applications. Engineers seeking a compact, high-current driver with thermal resilience will find the VB325SP a compelling solution, despite its discontinued status. For new designs, STMicroelectronics may offer alternative VIPower™ devices with updated features.
