The NIF5002NT3 is a Power Distribution (PD) Switch optimized for USB on-the-go applications. The device provides a low-cost alternative to active switches currently used in PD applications. Its low-power dissipation and FET-level logic input make it suitable for a broad range of application fields, from Cell-phones to PCs, from portable medical devices to tablets.

The main features of the NIF5002NT3 are its fast switching capabilities, low on-resistance, and low capacitive load. These features allow the device to provide improved power delivery to connected devices and improved system efficiency, resulting in overall lower energy consumption. Additionally, the NIF5002NT3 provides enhanced levels of safety with its built in over-voltage protection, current-limit protection, and fault protection.

The NIF5002NT3 consists of four independent, non-isolated PD switches. Each switch is a dual-source pick-up wide range switch, capable of driving two independent power sources. The activation of the switches is controlled by the polarity of a logic control signal. When the logic control signal is in a high state, the corresponding switch is activated, allowing current to flow to the load.

The NIF5002NT3 is a non-isolated device, meaning that the input and output devices are physically connected, allowing the device to deliver the full power it is able to supply and providing the added benefit of being more compact and cost-effective than an isolated device. This also means that the device is less tolerant of EMI/RFI noise, and therefore requires careful layout and trace length matching of both the input and output components if used in EMI/RFI sensitive applications.

The NIF5002NT3 is designed to handle up to 8A of continuous current while still maintaining an acceptable temperature rise when mounted on a thermal pad and operating in an ambient temperature of 25°C. The device can also handle up to 25V of input voltage. Furthermore, it has an operating temperature range of -40°C to 85°C.

In terms of application field, the NIF5002NT3 is suitable for powering applications such as USB PD chargers, charging docks, USB hubs, port replicators, mobile and automotive chargers, power bars, and power strips. It is also suitable for applications such as medical, computing, multimedia, and consumer electronics.

In conclusion, the NIF5002NT3 is a low-cost alternative for PD applications. Its fast switching and low on-resistance capabilities, combined with its fault, over-voltage, and current-limit protection, make it suitable for a wide range of applications. In addition to its low cost, the device also offers low power dissipation and a wide operating temperature range, making it an attractive alternative for many applications.
