Pin Description
PIN
NAME
FUNCTION
1
RESET
Hardware Reset. Pull RESET low for at least 300祍 to reset the device. All internal registers reset to their
default value. The address (A0A3), and AUTO and MIDSPAN input-logic levels latch on during low-to-
high transition of RESET. RESET is internally pulled up to V
DD
with a 50k& resistor.
2
MIDSPAN
Midspan Mode Input. An internal 50k& pulldown resistor to DGND sets the default mode to end-point PSE
operation (power-over-signal pairs). Pull MIDSPAN to V
DIG
to set midspan operation. The MIDSPAN value
latches after the IC is powered up or reset (see the PD Detection section).
3
INT
Open-Drain Interrupt Output. INT goes low whenever a fault condition exists. Reset the fault condition
using software or by pulling RESET low (see the Interrupt section for more information about interrupt
management).
4
SCL
Serial Interface Clock Line Input
5
SDAOUT
Serial Output Data Line. Connect the data line optocoupler input to SDAOUT (see the Typical Operating
Circuits). Connect SDAOUT to SDAIN if using a 2-wire, I
2
C-compatible system.
6
SDAIN
Serial Interface Input Data Line. Connect the data line optocoupler output to SDAIN (see the Typical
Operating Circuits). Connect SDAIN to SDAOUT if using a 2-wire, I
2
C-compatible system.
