• Manufacturer Part Number: max5952auaxt
• Description: Max5952 High-power, Quad, Pse Controller For Power-over-ethernet
• Manufacturer: Maxim Integrated Products, Inc.

High-Power, Quad, PSE Controller
for Power-Over-Ethernet
Writing a 1 to CLR_INT (Table 23) clears all the event
registers and the corresponding interrupt bits in regis-
ter R00h. Writing a 1 to RESET_P_ turns off power to the
corresponding port and resets only the status and
The ID register (Table 24) keeps track of the device ID
number and revision. The MAX5952’s ID_CODE[4:0] =
11000b. Contact the factory for REV[2:0] value.

reset to 0. Writing a 1 to RESET_IC causes a global
software reset, after which the register map is set back
to its reset state. A reset sets R1Ah = 00h.
