The demonstration circuit 1815A-A features the LTC?4266A quad power sourcing equipment controller, capable of delivering up to 38.7W of LTPoE++? power to a compatible LTPoE++ powered device. Advanced power management features of the LTC4266A include a 14-bit current monitoring ADC, DAC-programmable current limit, and versatile quick port shutdown. The LTC4266A includes an I2C serial interface operable up to 1MHz. The LTC4266A is configurable on the DC1815A-A as an AUTO pin high, MID pin high, autonomous midspan power injector; input data from an existing network system is sent out, along with power, to a powered device.
