The VN800PT is a high-performance, octal channel driver from STMicroelectronics, designed to deliver efficient and reliable control for a variety of automotive and industrial applications. This robust power driver is housed in a PowerSSO-24 package, which is engineered to provide superior thermal performance and space-saving benefits on the printed circuit board.

Key Features

• Channel Configuration: The VN800PT consists of eight independent channels, each capable of sourcing up to 0.7A of continuous current. This makes it highly versatile for driving a wide range of loads such as relays, solenoids, and lamps.
• High-Side Driver: It operates as a high-side driver, which means it connects the load to the positive supply voltage and switches the ground side, offering protection and control advantages.
• Protection Mechanisms: The device incorporates several protection features, including overtemperature shutdown, overcurrent shutdown, and load current limitation. This ensures the longevity and reliability of both the driver and the load it controls.
• Diagnostic Functions: Built-in diagnostic functions provide feedback on the status of each channel, including open-load detection when the device is off and real-time load current sensing, facilitating advanced control and monitoring capabilities.
• CMOS Compatible Inputs: The inputs are CMOS/TTL compatible, allowing for easy integration with a wide range of control circuitries and microcontrollers.
• Voltage Range: The VN800PT operates over a wide voltage range from 5.5V to 36V, accommodating various automotive and industrial power systems.
