The TPS23861 is an easy-to-use,
flexible, IEEE802.3at PSE solution. As shipped, it automatically manages four
802.3at ports without the need for any external control.
The TPS23861 automatically detects
Powered Devices (PDs) that have a valid signature, determines power requirements
according to classification and applies power. Two-event classification is supported
for type-2 PDs. The TPS23861 supports DC disconnection and the external FET
architecture allows designers to balance size, efficiency and solution cost
requirements.
The unique pin-out enables 2-layer PCB
designs via logical grouping and clear upper and lower differentiation of
I2C and power pins. This delivers best-in-class thermal performance,
Kelvin accuracy and low-build cost.
In addition to automatic operation,
the TPS23861 supports Semi-Auto Mode via I2C control for precision
monitoring and intelligent power management. Compliance with the 400ms
TPON specification is ensured whether in semi-automatic or automatic
mode.
