The LTC4255 is a quad –48V network power controller with independent relay drivers and I²C compatible interface. Each channel can be turned on and off via software control, while providing short-circuit protection, open-circuit detection, and power good indication. The short-circuit protection includes a current foldback feature to reduce power dissipation in the switch during shorts and start-up.

The serial interface allows up to 128 channels to be controlled with only two digital lines. A FAULT output can be used as an interrupt line to eliminate fault detection by software polling.

External switches and current sense resistors allow easy scaling of current and power dissipation levels and provide the maximum protection against voltage and current spikes.

The LTC4255 is available in the 28-pin SSOP package.
