(PSEPM)
that
are
compliant
to
the
Fault detection
power-over-ethernet (PoE) IEEE 802.3af Standard. A
Input Undervoltage Lockout (UVLO)
PSEPM port can discover, classify and deliver power
to a powered device (PD) capable of accepting PoE
Load Overcurrent and Undercurrent Detection
twisted
pair
cable.
The
TPS2383B
is
fully
12-Bit Port Current and Voltage Acquisition
programmable by the user. This allows for the detec-
Standard Slave I2C Serial Interface
tion and powering of both fully compliant 802.3
devices as well as custom detection of legacy de-
5-Bit Serial Address Selectability
vices.
