PMIC - Power Distribution Switches, Load Drivers, are one of the most important components in power supply and control systems. The VNQ81013TR, specifically, is an IC load switch offering high load current and high load voltage that is ideal for power management applications. It offers a broad range of features and can serve as the primary power switch for applications that require higher currents and voltage levels.

The VNQ81013TR features a low RDS(ON) (On-state resistance) as well as a fast turn-on and turn-off capability. It also has excellent thermal performance and requires only minimal external components for efficient circuit operation. The switch also has several integrated features such as over-voltage protection, over-temperature protection, over-current protection and short-circuit protection.

The power switch is available in two versions. The first version is the VNQ81013TR-1, which offers a single low-side power switch with pinout compatible version of the Infineon PS8303. The second version is the VNQ81013TR-2, which offers two high-side power switches with a single fault line. Both versions are designed to handle high current loads with minimal power dissipation.

The VNQ81013TR application field is primarily for power management circuits. Applications can be found in a number of markets including consumer electronics, automotive, industrial and white goods applications. The VNQ81013TR can be used to control the flow of power between various components in a system and can deliver up to 4 A of continuous load current with a 35V maximum voltage.

The working principle for the VNQ81013TR power switch is fairly simple. There are two kinds of signals it responds to: an Enable signal and a Fault signal. The Enable signal is used to turn the switch on and off. When the Enable signal is low, the switch is off and no current passes through; when the Enable signal is high, the switch is on and current flows through. The Fault signal is used to protect the device in case of an overload or short circuit condition. If the fault signal is low, the power switch is automatically disabled and the current is blocked.

In summary, the VNQ81013TR is a power switch that offers a high load current and voltage rating with fast turn-on and turn-off performance, high thermal performance and over-voltage, over-current, over-temperature and short-circuit protection. It also offers two versions to satisfy different applications. The working principle is straightforward and simple with only two signals needed for operation. The VNQ81013TR is an ideal solution for applications in consumer electronics, automotive, industrial and white goods power management needs.
