The MAX14954ETO+ is an integrated USB I/O switch designed to route USB signals from one source to multiple downstream USB ports. This type of integrated converter is part of the Interface – Signal Buffers, Repeaters, Splitters category, due to its ability to transmit data wirelessly at high speed. Its application field and working principle are discussed here.

The MAX14954ETO+ is used in applications where multiple downstream USB ports need to be connected to one USB source without physical cables. It takes the incoming signal from its source and splits it equally among the four downstream USB ports. This results in easy setup and greater flexibility in a wide range of data transfer applications, including gaming consoles, set-top boxes, printers, and other USB 2.0 devices. The device is also compatible with USB 2.0, 1.1, and 1.0 specifications, allowing for greater versatility.

When it comes to usage, the MAX14954ETO+ can be connected to the source via its USB full-speed host port. The USB data signals are then routed through the IC’s internal logic and then split equally among the four downstream ports. The ports use a buffered output configuration and they are rated to deliver up to 500 mA of current each, making them suitable to drive heavier USB peripherals. The device also offers automatic switching, with four indicators (LEDs) to show which port is in use at any given time and users can switch port selection through the programming pins.

The MAX14954ETO+ is based on primium CMOS technology and its output logic is fully compatible with the industry-standard 2.0 OVP. It also features an internal voltage regulator that meets the OVP requirements, allowing for worry-free operation in a wide range of hot-swapping applications. The device also features an integrated over-current protection (OCP) circuit offering enhanced protection against downstream faults.

Additionally, the MAX14954ETO+ also offers an integrated power-on reset circuit to ensure compliance with all USB speed grades. This ensures reliable operation in all aplications, especially when multiple downstream ports are connected to the same source. It also features ESD protection, making it highly reliable and durable in the face of harsh and sudden static discharges.

In conclusion, the MAX14954ETO+ is an integrated USB I/O switch designed to route USB signals from one source to multiple downstream USB ports. It features automatic switching and buffered outputs, allowing for hassle-free setup in a wide range of applications. The device also offers integrated ESD, OVP, and OCP protection, making it highly reliable and durable in the face of harsh static discharges. It is a great choice for applications that require multiple downstream USB ports connected to a single source.
