The VNP35N07-E is a 3rd generation N-Channel MOSFET power distribution switch, load driver, and power management integrated circuit (PMIC) designed for automotive and industrial applications. It is designed to provide low power management with improved power handling capacity and control. Its versatile integrated circuit (IC) offer an array of features that can be utilized to optimize power efficiency and cost.

Application Field

The VNP35N07-E is primarily used to control the distribution of power in automotive and industrial applications. In automotive applications, it can be used to control the voltage supply to critical systems such as the lights and other components. Furthermore, it can be used in industrial applications for supply switching between different stages of production or for power system regulation.

Working Principle

The VNP35N07-E is based on an N-channel MOSFET circuit, which is designed to exhibit low on-state resistance while maintaining a low stand-by power consumption. It provides optimized power transfer efficiency and improved scalability, while also providing a low VEC threshold voltage. The integrated current sense circuitry provides the protection against over-current and short-circuit conditions. The integrated N-channel MOSFET switches provide excellent performance in terms of on-state resistance, efficiency, precision and reliability.

The VNP35N07-E can be used to enable/disable the load power supply line. This is done by controlling its gate voltage and current from a low voltage supply, allowing the switch to be accurately controlled and monitored. The integrated control circuit monitors the current through the load line and works in conjunction with the N-channel MOSFET switches to adjust the power delivery accordingly. The integrated monitoring circuit also measures the gate voltage and current to provide feedback to the user.

The VNP35N07-E provides protection against over-current and short-circuit conditions by utilizing the integrated current sense circuitry. This feature works by measuring the voltage drop across a sense resistor connected between the source and drain of the control MOSFET. The current sense amplifier is used to convert the voltage drop into a current value, which is then compared to a preset threshold. If the current value is greater than the predefined threshold, the device will open and disconnect the power path, consequently providing protection against damaging currents.

The VNP35N07-E is designed to be compatible with various operating systems, such as LIN and CAN protocols. It has an excellent operating temperature range of -40°C to +150°C, making it suitable for harsh environmental conditions. Additionally, it has an adjustable refresh rate which can be adjusted for optimal power saving performance.

Overall, the VNP35N07-E power distribution switch, load driver and power management integrated circuit (PMIC) is a versatile and efficient low power solution for automotive and industrial applications. Its integrated current sense circuitry helps protect against over-current and short-circuit conditions, while its N-channel MOSFET switches provide improved precision and reliability. With a wide operating temperature range and adjustable refresh rate, the VNP35N07-E is a reliable and cost-effective solution for power distribution switching, load driving and power management.
