The IEEE 1394, which is also called FireWire by Apple, is an interface standard for high-speed serial bus for connecting devices to a personal computer. Like USB, IEEE 1394 is a serial bus that uses twisted-pair wiring to move data around. However, USB is limited to 12Mbps, IEEE 1394 currently handles up to 400Mbps. The reference design illustrates single and dual port FireWire protective circuits. The single-port FireWire protective circuit is designed using the MAX5943A, while the dual-port FireWire protective circuit utilizes the MAX5944.
The circuit provides a 2.5A adjustable current limiting to the load at initial connection or during an overcurrent fault condition. It also provides 2ms adjustable current-limit timeout for excessive load current. It automatically attempts to restart after a fault shutdown condition. Some other features involve; less than 8 percent current-limited duty cycle during continuous fault condition, 6.5V undervoltage shutdown protection, low-drop O-Ring in multiple-power-source applications, and fault reporting. The FireWire port used in this design is the TE Connectivity’s 1734290-1. This connector conforms to IEEE 1394 standard with easy connections to equipment for use with plug and play devices.
