Introduction

The VND7NV04 Power Management Integrated Circuit (PMIC) is a power distribution switch and load driver designed for automotive applications. It is designed for applications that require an efficient, reliable, and cost-effective power distribution platform. The VND7NV04 includes an integrated load driver, which provides a high level of output power accuracy, allowing power to be distributed to multiple loads with minimal distortion. It also features advanced protection features, including an input voltage lockout (VL) and output short protection (OSP) feature. The VND7NV04 can operate with an input voltage range of 5 to 28V, an output current capacity of up to 10A, and a switching frequency of up to 15MHz.

Application Field

The VND7NV04 is designed for power distribution in a wide range of automotive and other applications. It is suitable for medium and large loads such as automotive appliances, Head Unit, Vehicle Body Control Modules, Automotive Lighting (LED and halogen), MEMS Modules, and other electronic and automotive applications.

Working Principle

The VND7NV04 is a voltage-mode synchronous buck converter with a maximum switching frequency of 15MHz. It allows the user to select an economical and efficient power delivery profile, providing excellent transient response and reduced power switch losses.The VND7NV04 employs an adaptive current mode control (ACC) technique which enables optimized control of inductor current and output voltage ripple. This also reduces the switch losses for power efficiency. The VND7NV04 is capable of handling high side and low side current shunt detection, thereby improving the overall regulation and ruggedness of the design.In order to ensure proper operation, it is important to check the enable pin and the fault pin of the VND7NV04. The enable pin, when high, enables all the power switches of the device and, when low, disables them. The fault pin is active low when a fault is detected; when high, no fault is detected in the VND7NV04.

Conclusion

The VND7NV04 is a power management integrated circuit (PMIC) suitable for automotive and other applications. It features an integrated load driver, advanced protection features, an input voltage lockout (VL) and output short protection (OSP) feature, and an adaptive current mode control (ACC) technique. It is capable of handling high side and low side current shunt detection, enabling optimized control of inductor current and output voltage ripple, improving the overall regulation and ruggedness of the design.
