DC1682B Datasheet, PDF (11/26 Pages) Linear Dimensions Semiconductor – 12-port Type 2 power sourcing equipment (PSE) composed of a DC1682B daughter card and DC1680A mother board.

DEMO MANUAL DC1840B
Demonstration Circuit 1680A Operation
Interrupt LED
Port 1 Through 12 Power LED Indicators
A red LED indicates when the INT line is pulled logic low
by the daughter card. When the interrupt is cleared (high)
via I²C servicing, the LED is turned off.
Each PSE port has a green LED indicator to show when
PoE power is present at the port. The LEDs are driven by
the respective port OUT voltage.
