The VN7003AHTR can be classified as a PMIC (Power Management Integrated Circuit) – Power Distribution Switches, Load Drivers. It is a three-channel power switch that can be used to manage multiple loads, enabling system architects to connect up to three power-intensive loads from a single supply. The switch has a low output current limit, allowing it to operate at a maximum of 24 V and 0.6 A. It also features an integrated dual-channel analog current-foldback (ACF) protection. This device is designed to improve system reliability and power management with low power consumption.

VN7003AHTR Application Field

The VN7003AHTR is ideal for applications in which multiple power-hungry loads need to be managed. It is suitable for a variety of system-clocking applications, such as clock trees, power sequencing and synchronization, as well as data transmission and storage. The device can be used to safely supply multiple loads with a dedicated power source and is robust enough to handle thermal stress and over-current protection limits of the system.

The device is designed to minimize power dissipation and thermally-induced board temperature rise in industrial and commercial applications. It can be used in a variety of system architectures, such as power over Ethernet (PoE), DC-DC converters, hot-pluggable loads, multi-channel power distribution systems and general-purpose systems.

VN7003AHTR Working Principle

The VN7003AHTR is a 3-channel power switch that allows up to three separate loads to be switched on and off independently. It is designed to have a low power dissipation rating and a low thermal resistance, making it suitable for many applications in which low power consumption and high efficiency are desired. The device has integrated ACF (Analog Current-Foldback) protection, which ensures that all three loads can be powered simultaneously without damaging the switch.

The device operates in one of three modes: Sleep, Standby, and Active. In Sleep mode, the device is powered down, drawing negligible current. When the device is in Standby mode, it draws a small amount of current and powers the loads while monitoring their voltage and current levels. In Active mode, the device is fully powered and controls the current going to each load, allowing it to efficiently manage up to 3 power-hungry loads independently.

The device also features an integrated dual-channel start-up protection circuit, which prevents any inrush current when loads are switched on. This allows the VN7003AHTR to more efficiently manage the power consumption of up to three power-intensive loads, ensuring a higher system performance with lower power consumption.

In addition, the VN7003AHTR can be used as a power supply controller, allowing the system designer to monitor the power consumption of multiple power-intensive loads. This allows for improved system reliability and system stability, as the switch can detect any potential fault conditions and adjust the power settings accordingly.
