VN7007AHTR Integrated Circuits (ICs)

Power management integrated circuits (PMICs) are specially designed integrated circuits intended to govern power flow in electronic systems such as electronic filters, controllers, drivers, and other components. PMICs are complex systems that are efficiently miniaturized and manufactured to handle many devices and power distribution for very reliable and efficient current, voltage and temperature monitoring. Among them, power distribution switches, load drivers, and other components are the most important elements in power management.The VN7007AHTR is a high-efficiency power supply controller in a 5-channel power supply system. It integrates 5 high-side switches and 5 low-side switches with an over-current protection circuit and logic/safety signals. The VN7007AHTR is available in a space-saving 16-pin, single sided QFN package that allows for flexible layout and is ideal for smart home and automotive power integration.

Application fields

The VN7007AHTR is suitable for power management in the smart home and automotive industries. It is suitable for a wide range of industrial applications including robotics, medical, security, and automation control. It supports applications such as motor control, LED lighting, and battery management. It is also used in consumer products such as mobile phones, tablets, and wearable devices. It is well-suited for energy-efficient designs, providing 30 % power saving under light load conditions. The VN7007AHTR is a highly integrated, low power device and is one of the most popular devices for power management applications.

Working principle

The VN7007AHTR is a high-efficiency power distribution switch for power management. It contains 5 high-side switches and 5 low-side switches with built-in over-current protection circuits, which can be used to protect the power supply from over-current conditions. The VN7007AHTR includes internal logic signals to monitor the status of the power system, including power on/off, enable, fault and reset. The VN7007AHTR also includes a load current setting circuit, which can be used to adjust the load current according to different applications. A built-in temperature sensor can monitor the temperature of the device and accurately report faults.

The VN7007AHTR switching elements can handle both continuous and short pulse loads. In order to provide high efficiency at light or medium load conditions, the VN7007AHTR supports Active-High and Active-Low modes, as well as PWM, PFM/PSM and Tiny Buck modes for power saving. Additionally, the VN7007AHTR supports synchronous rectification for improved efficiency and a logic signal for improved system monitoring.

The VN7007AHTR is carefully designed with built-in protection circuit, stable and reliable operation, easy system monitoring, compact package, and low power consumption, making it an ideal choice for power management systems.
